The closer is a device for returning the door to its original position in automatic operation. This device silently and softly closes the open sash. If necessary, it holds the door leaf open. Many doors are equipped with a modern practical fixture. At the same time, like any technique, the door closer needs maintenance, adjustment and troubleshooting.

Types of mechanisms and their structure

To better understand the principle of the mechanism's functioning, you need to analyze its basic varieties, so it will be easier to figure out how to correctly debug the door closer.

For the most part, these two types of this device are practiced:

• cam slide - performs soft sliding, is practiced for blades with light weight;

• toothed lever - the most common type of mechanism, the movement of the spring is realized by means of gears, it can be used even for massive door leaves.

According to the method of mounting, the fixtures can be divided into three main types:

• Overhead structures (overhead)- these are the most straightforward devices to use, their functions can be adjusted by means of several screws or valves located on the body panel. They are mounted in the upper part of the sash, which is extremely convenient for installation. For entrance street doors, specialized oil-filled devices are manufactured, adapted to function in hot or cold climates.

• Outdoor. Floor-mounted systems are also relatively easy to set up. They showed themselves excellently in banking institutions, offices, shopping and entertainment complexes and where there are high demands for the external appearance of doors. These devices are integrated into the floor and are almost invisible to visitors. Sliding type regulator mechanisms are used, designed for doors weighing no more than 100 kilograms.

• Concealed devices it is quite problematic to adjust it on your own, since they are removed inside the door leaf or into the floor, which complicates access to them. The devices are in demand wherever a thorough cosmetic finish and a perfect main façade are required.

According to the principle of operation, the devices are as follows:

• hydraulic;
• pneumatic;
• electrical.

Fixture structure

The structure of this device the following parts and mechanisms are included:

• die-cast aluminum body;
• spring;
• piston;
• adjusting screws (valves);

• gears;
• needle bearing;
• rubber seals;
• fasteners.

The principle of the closer

The basic component of the structure is a spring system, which, when the door is opened, is compressed and accumulates the energy required to close the door. The squeezing process is carried out by transferring the force of the traction device to the spring. Toothed gears and racks move the piston, while the oil flows through the internal channels into the free part of the housing. During the reverse movement of the door, the spring expands and provides a soft close.

When is the procedure necessary?

Adjusting the door closer function is quite simple. The setting can be done without any problems with your own hands. It is worth figuring out in what situations it may be necessary to adjust the parameters of this mechanism. The first thing to remember is that the duration of the uninterrupted operation of any mechanism is directly based on the quality of its maintenance during the entire period of operation. As a result, 1-2 times a year, it is required to inspect the closer and eliminate minor malfunctions. This is especially important during the transitional change of seasons.

Climatic conditions vary enormously in summer and winter. Most of the closers are filled with oil, and as you know, any liquid changes its state when the ambient temperature changes. In particular, in winter, the oil becomes thicker and the door leaf travels slower. In the summer, everything turns out to be the opposite, therefore, it is required to prepare the closer to the required level. Adjustment of the device is also necessary if you notice any malfunctions or you just do not like the settings you have set. If the device starts to slow down or the door leaf closes too hard and quickly, irregularly, does not attract for a long time, all this can be tried to be corrected. Things are somewhat more complicated when the device is out of order, since a simple adjustment will no longer be effective and repair work will be required.

Instructions for setting up a door closer with your own hands

It is not necessary to invite an expert to adjust the device. You just need to have a minimum set of tools and certain skills. The whole procedure will take a minimum amount of time and will make it possible to achieve the desired result by adhering to the steps listed below.

• Before proceeding with the procedure itself, remember that the main thing is not to overdo it with the control valves (screws). It is acceptable to make only 2 turns, then complications can appear. The oil in the pressurized reservoir can spill out and the hydraulic system of the closer will eventually become ineffective.
• To adjust the closing speed of the door leaf, it is necessary to learn only one tendency - turning the valve clockwise, it will gradually decrease. If the action is performed in the opposite direction, the closing speed will increase.

• The problem that only one person can get through has a solution. Since there is a third valve, the adjustment of which can provide the door with a stationary position for a certain time. Consequently, even a group of people will be able to freely enter the premises.
• Such a problem as the lack of force to completely close the door leaf is eliminated by adjusting the valves responsible for the closing speed.

Finding the perfect solution can be a key challenge when adjusting a door closer. The main task is to close the door to the end so that no gaps remain. It is necessary to correctly choose the ideal time that the door leaf can remain open. It is also required to make possible silent closing, hard blows against the door frame are unacceptable. This can cause damage to the canvas. And the worst option may be the loss of performance of the mechanisms responsible for proper operation.

How to adjust the closing force so that the door does not bang?

For self-adjustment, you need a flat-end screwdriver or an imbus wrench. The door opens to the end, special valves are fixed, located at the end of the device. Full fixation is performed when the door leaf is closed. By changing the degree of tightening of the valves, you can adjust the door to an extremely comfortable closing. Valve number 1 is responsible for the closing force of the door.

If the fully open door closes too quickly at the beginning, the valve must be tightened, and if it is slowly and necessary to increase the speed, on the contrary, it must be unscrewed. Valve number 2 is responsible for the speed at which the door leaf is fully closed (slammed). Some modifications have a third valve, which adjusts all the efforts of the closer functioning. With proper tuning, the door leaf moves smoothly, without jerking. Correct installation and competent attitude of the closer will result in a long service life.

Important! Do not turn out the control valves at all. Otherwise, they will cease to carry out their functional purpose even after they are returned to their place.

How to weaken the opening?

Quite often, the closer requires additional adjustment. If the mechanism works tightly, and in the process of opening the door it is required to exert effort - it is necessary to release the valve, the door will begin to function smoothly. The valves can be placed from the end or on the front side, it all depends on the modification of the device. You can find out the location of the valves by looking in the manual, where the manufacturer indicates the location of all components and elements of the door closer mechanism.

Position open

At times, there is a need for an open door over a relatively long period of time. It is worth figuring out how to adjust the device so that the doors do not close, but remain open. In many door closer versions, there is an auxiliary hold open option for this. To adjust it to this mode, you need to open the door approximately 90 degrees, and then tighten the specialized latch. After such simple actions, it will be possible to leave the door leaf open when opening it to the configured degree. A special latch will be activated in the device and will hold the door in this position as long as necessary. If you need to close the door, you just need to pull it towards you, and it will be removed from the latch. If you do not open the door to the limit, it will move in the same way as always, without stopping.

Modern doors are equipped with a special device that relieves households from the need to slam the door after themselves. However, in this case, the door will not slam shut, but smoothly close behind you without unnecessary noise. This is, of course, a door closer. This small device requires special attention to itself, so it is so important to know how to properly adjust the door closer and carry out timely repairs.

Features of door closers

The problem of open doors can be easily solved by installing a door closer that controls the process of automatically opening and closing the door, closing it without additional force from a person. The need for door closers is dictated by fairly practical and functional reasons. Let's say you put in a massive metal entrance door. The door leaf has a large mass, and if you do not specifically hold the door when closing, the door leaf will hit the loot with great effort.

Door closers ensure smooth door closing without unnecessary noise, set the speed of closing and opening the door in different areas, and also determine the effort that a person must apply to open the door. The door closer is able to save heat or coolness in the room, as well as ensure the correct operation of the locking device. In addition, closers with the hold open function support the possibility of holding the open door, which is very useful, since you do not have to put any objects under the open door.

Closers with a delay action mechanism allow the doors to be left open for a certain period of time, after which the door will close normally. This type of device is considered convenient for doors in utility rooms (warehouses, utility rooms, closets). This model is suitable so that you can open the door when carrying loads, then take the load, bring it into the building, and after this time the door starts to close itself without requiring mechanical effort.

Closers can be installed on ordinary interior and exterior heavy doors, taking into account the preliminary weight of the door and the width of the door leaf, and also not forgetting about the need to adjust the door closer. The heavier your door is, the more reliable and powerful the door closer should be for it. The simplest version of the mechanism is considered to be a spring. But such a "closer" works too abruptly and very noisy.

The ideal option is an adjustable design, which is also based on a spring, but it is enclosed in a sealed housing in an oil composition. The principle of operation of a door closer is quite simple. To open the door, a person applies a certain force, which is transmitted mechanically to the door closer and accumulated by compressing the spring that is built into the door closer body. This spring then returns to its original position, allowing you to adjust the closing process of the door.

Types of door closers

By design, door closers are divided into lever versions, which are equipped with a crank drive, and leverless models with a cam drive.

Inside the lever door closers there is a spring and a hydraulic system that is filled with oil. The hydraulic system acts as a shock absorber. The spring is compressed when the door is opened, and the liquid is pushed out by the piston from one container to another. After that, the spring is straightened, and the oil is returned to the first container. Although the hydraulic spring is located in a sealed box, sometimes it starts to leak, which is the first signal to repair the door closer.

The system contains valves that regulate the rate of fluid flow and the force at which it will move. They are responsible for the speed and smoothness of the door closing. The door closer device can be complicated by additional valves that provide different functions of the door closer. For example, holding the door open for a long time, or creating a latching function to activate the lock or better press the door to the door.

According to the method of installation, door closers are divided into:

• closers for surface installation, which are installed on top of the wall, door frame or door leaf, according to the door closer diagram;
• for hidden installation that are mounted inside the door; for floor installation, when the closer is hidden in the floor.

If the overhead door closer does not fit into the design of the room, you can always install an "invisible" device that will hide in the specified place and will be practically invisible. But there are also different decoration panels for overhead models, or they can be painted in a chosen color.

Methods for installing a door closer

Installing a door closer does not require special preparation, so you can cope with this task without any problems. As a rule, all the necessary parts and tools are included in the package. There are four ways to install a closer, let's take a closer look at them.

1. The easiest way to install a door closer is described in the instructions for it. It looks something like this: the lever arm is fixed on the device body, then, using the template that is attached to the instructions, the places for fastening the screws are outlined, then the screws are screwed in according to this marking. The main thing to remember is that you will also need to adjust the geze door closer.
2. The second method of installing a door closer involves the following. It is necessary to attach the closer to the door in such a way that its adjusting screws are facing the door hinges. Next, you need to fix the shoe of the device with the screws that are included in the kit with the closer. Remember that the "forearm" of the device lever must be of such a length that a right angle is obtained with respect to the door. The shoulder is attached to the shoe with screws, after which you will again have to think about how to adjust the door closer.
3. If you follow the third method of installing a parallel arm door closer, then you need to insert the device lever under the door block, and then fold it outside the room. In this case, the closer is attached with a bracket, which is also included in the delivery set. When installing the closer, make sure that the adjusting screws rotate from the hinges in the opposite direction. It is important not to confuse anything during the installation process, otherwise incorrect installation will lead to the fact that it will not be possible to carry out the optimal adjustment of the door closer.
4. There are door closers that use an adjustable spring. It is easiest to install such devices: you need to replace the hinge rod with a closer - and you're done. The main thing is that the product corresponds exactly to the weight of the door. If the door leaf is too heavy, and you could not find a suitable door closer on sale, you need to install not one, but several door closers.

DIY door closer repair

Correct operation of the door closer is the key to its conscientious and long-term work that does not require repair. In order for the door closer to work for a long time, you cannot pull or hold the door, thereby helping it to close faster or slower. It is not recommended to fix the door by placing various objects under it that prevent it from closing, as well as rolling and hanging on the door (this applies to children).

To repair the door closer, you need to have all the necessary tools at hand (hex and wrenches, pliers and a set of screwdrivers). Before proceeding with the repair of the device, you should make an external inspection of the door, since its distortions or damage will interfere with the normal operation of the closer.

Unfortunately, serious damage to the door closer cannot be repaired, since the tightness of the structure means that it cannot be disassembled into separate parts and subsequently assembled in accordance with technology. Nevertheless, in some situations, it is possible to repair the closer and adjust its work independently. Let's take a look at how to repair a door closer:

1. Leakage of the oil composition. Regardless of the fact that the hydraulic spring, which transfers the generated voltage to the levers, is located in a one-piece sealed box filled with working fluid, its leaks still occur, most often in winter. If a leak appears, then this indicates a depressurization of the case and the appearance of damage, from which oil flows out. As a result, the mechanism ceases to smoothly bring the door, slams loudly and turns into an ordinary spring. If you were able to find damaged areas in a timely manner, you need to seal them, which helps to extend the service life of the device. However, if the damaged area is too large, then it will not be possible to repair the door closer with your own hands and you will have to buy a new door closer.
2. Breakage of the lever assembly. The most common is the violation of the integrity of the rods. However, this part of the mechanism is always visible, so its condition can be assessed visually. Large force effects can disable it, causing kinks, bends, distortions or damage to the fasteners. You can fix not very serious flaws in the rod using ordinary welding. If there is a breakdown of the fastening connection, then it is possible to carry out repairs by purchasing new original parts that are suitable in size, fastening method and shape of the seat.

Do-it-yourself door closer adjustment

Significant loads during intensive use of a door closer often provoke a breakdown of the entire system. Therefore, it is recommended to closely monitor and service it several times a year, especially when the weather changes. But if the system does start to malfunction, then you should find out how the door closer is regulated.

The closer adjustment procedure includes several points, the main one of which is changing the speed of movement. If the door leaf is opened too slowly, the spring compression level must be adjusted using the appropriate lock nut. The door travel speed is set by rotating the first valve (counterclockwise and clockwise).

You can turn the first valve no more than 2 turns, which is negotiated by the door closers manufacturers. The second valve is responsible for latching - the gap when the door is in a state of 10 - 15 degrees until it is completely closed. More expensive models also have a third valve in their design, which is necessary to adjust the door closing speed at an angle of 80-90 degrees.

If a specialized oil is used in the door closer body, then with the onset of winter you may notice that the door closer speed drops in cold weather, and in summer the mechanism, on the contrary, accelerates. This is explained by the fact that the viscosity of a liquid depends on temperature. Therefore, with the onset of winter cold, it is necessary to additionally adjust the door closer by adjusting the first valve.

It is often necessary to hold the open door in this position for a while. An increase in the delay of the door leaf before closing can be achieved by tightening the special retainer more tightly. It is customary to perform this manipulation when the door is open approximately 95 - 100 degrees. The open position of the door is also monitored using a specific door closer option.

If the door needs to be kept open for a long time - to move furniture or ventilate the room, then you should use the hold-open function of the closer. Such a device is equipped with a lever for locking the door in the open position. You should open the door 90-95 degrees and tighten the latch. After such manipulations, the door will close normally if you open it at a smaller angle than 90 °. If you open the door wider, it locks in place and remains open until you pull towards yourself, thereby releasing the lock.

In some cases, it may be necessary to change the opening angle of the door. If necessary, you can change the opening angle of the door using a special valve, which should be turned counterclockwise or counterclockwise. The main thing when adjusting the closer is not to disrupt the functioning of the system: you cannot turn the screw more than 2 full turns, it is undesirable to tighten the screw all the way, it is forbidden to completely unscrew the nuts and adjusting screws.

If you have tried all of the above tips on how to set up a door closer, but nothing helped, then perhaps the whole problem lies in the wrong installation. Check the vertical installation of the door and the correct installation of the door closer. Check the placement of the nut that adjusts the tension of the spring, remember that it should be against the door hinge. The lever must be of such length that it is at right angles to the door frame. If you have the slightest suspicion that you have installed the door closer incorrectly, it is recommended to remove it and put it in accordance with all the rules.

Thus, without much expense, having a screwdriver and 5 minutes of free time at your disposal, and knowing the technique of how to adjust the door closer, you can independently adjust this mechanism. The main thing is to remember some of the features of the work, which allow not to disrupt the correct functioning of the system.

About what functions are found in door closers, why they are and whether they are always so necessary.

1. WHAT FEATURES ARE AND HOW DO THEY WORK?

The Palladium door closers, like any other gear-driven overhead door closers, have basic and advanced functions.

The basic functions are Close Speed ​​and Latch Speed. Additional: wind brake (Back Check), closing delay (Delay Action) and hold in open position (Hold Open). All functions work independently of each other. And everything, except for fixing in the open position, can be adjusted.

Let's explain how it all works. The closer body is filled with viscous machine oil. It also contains a spring, a piston and a hydraulic system, which consists of channels through which the oil moves back and forth. Opening the door, we act on the piston, and it compresses the spring. At this time, the oil flows from its starting point to another part of the body.

When we release the handle, the spring expands and presses on the piston - the door starts to close. At the same time, the spring pushes the oil. It passes through the channels and flows through the valves into the channel from which it began its journey. Therefore, a door controlled by a door closer does not just close, but does it smoothly.

The idea is to partially block the desired channel with the help of adjusting screws, controlling the oil flow rate, and with it the smoothness of the door closing. The screws are adjusted with a screwdriver. The main thing is not to unscrew them counterclockwise two or more turns from the factory setting, otherwise the screw may fall out, and the closer may leak. In general, in order to feel the change in the course of the door, it is enough to tighten the screw 1 / 8-1 / 4 of a turn.

We described how the top closer functions work. Now let's take a look at each of them separately. However, keep in mind that all values ​​(degrees, seconds) are approximate and are given for installing the closer in a standard way (perpendicular lever).

2.ADJUSTABLE CLOSING SPEED (CLOSE SPEED)

[What is he doing]

Accelerates or slows down door closing within a range of up to 15 °. That is, on the way from the "open door" state to the "door is about to close" state.

[Description]

Avoid extremes when adjusting your speed. If the door closer closes the open door quickly (less than 4 seconds), it will inconvenience children, the elderly and the disabled. If it is slow (more than 7 seconds), and the door is front, in winter you can let the cold into the room.

Please note: for door closers with a delayed closing (Delay Action), the Close Speed ​​function is activated in the range from 69 ° to 15 °. The speed of the web from 180 ° to 70 ° depends on how you set the closing delay.

[How to adjust]

Turn the corresponding screw clockwise to make the door close more slowly. If you want to speed up closing, turn the screw counterclockwise.

All Palladium and Castle Factories models

3.ADJUSTABLE LATCH SPEED

[What is he doing]

Accelerates or slows down the door closing in the range from 15 ° to 0 ° (at the very end of the leaf movement).

[Description]

This function is needed for automatic slamming. If you accelerate the finishing, then the door controlled by the closer will make a "jerk at the finish". This is enough for it to enter the seal and close with a mechanical latch (no debugging is needed for magnetic locks). And vice versa. If there is no seal and mechanical latch, the stitching can be reduced. Plus, there will be less rumble and pinching of your fingers.

[How to adjust]

Turn the screw clockwise to reduce lapping. If you need to increase it, turn the screw counterclockwise. Important: first adjust the closing speed and only then adjust the finishing speed, and not vice versa!

All Palladium and Castle Factory models.

4.ADJUSTABLE WIND BRAKE (BACK CHECK)

[What is he doing]

Limits sharp opening or slamming of the door in the range from 70 ° to 180 ° (depending on the adjustment).

[For what]

To prevent the wind and hooligans from knocking the door against the wall, harming the hinges and handles. This option is suitable for exterior doors and entrances with high traffic and risk of vandalism (educational institutions, shopping centers, hospitals, etc.). We also recommend it if the room is located in a windy area.

[Description]

With a sharp movement of the door, damage is caused not only to the fittings and the wall, but also to the closer. Especially the spring-loaded piston. It has a polyurethane sealing lip. If the door is pushed open or slammed with force, then the water hammer will be right on the cuff. She is not ready for such loads, therefore, most likely, it will burst and leak. But even if the cuff is lucky, the closer link arm may suffer.

To prevent all this from happening, the door closer is equipped with a hydraulic "wind brake". It works like an airbag for the door.

The wind brake cannot be turned off, but it does not interfere with the use of the door. The fact is that the resistance of the closer is proportional to the speed of the web. That is, the damping is activated only when the door moves quickly, with a jerk. And if it is smooth, as usual, then you will not feel any resistance. In addition, you can always tighten the adjustment screw by setting the desired angle and damping stiffness.

[How to adjust]

Turn the wind brake screw clockwise to harden the damping and release earlier. If you want to loosen the shock absorption and let the door swing open more, turn the screw counterclockwise.

5.ADJUSTABLE CLOSING DELAY (DELAY ACTION)

[What is he doing]

It slows down the door closing speed several times in the range from 180 ° to 70 °. After passing the 70 ° angle, the door closes at normal speed. The maximum delay time depends on the door closing angle, the set adjustments and can be up to 35 seconds.

[For what]

You no longer need to ask others to hold the door for you if you need to bring in boxes, carry a stroller or cart.

[Description]

Door closers with Delay Action function are suitable for utility rooms (warehouses, storerooms, utility rooms, etc.). A delay of up to 35 seconds is enough for workers to place the load, open the door, lift the load and bring it into the room. This feature is also useful in healthcare facilities and nursing homes. It will be easier for hospital and hospital staff to carry stretchers and roll carts. The elderly and patients in a wheelchair will be able to safely use the door.

Closing delay cannot be disabled, but can be reduced to a few seconds. Keep this in mind if you are going to install a door closer with this function on doors with a high capacity (for example, in large shopping centers). It is also not the best option for a front door in a constantly air-conditioned room.

[How to adjust]

Turn the corresponding screw clockwise to increase the delay time. If you don't need a long delay (for example, in freezing temperatures on the entrance doors), then turn the screw counterclockwise.

6.FIXING THE OPEN POSITION (FOP, HOLD OPEN)

[What is he doing]

Stops the door and prevents it from closing when it is open at an angle> 70 ° -80 °.

[For what]

To leave the door open for a group of people to pass, carry cargo, transport a trolley, stroller, etc. Or for ventilation or cleaning.

[Description]

FOP is a useful option for interior doors, replacing the floor lock. When you open the door 70-80 ° or wider, it locks and stays open. To make it shut, "help" it: pull the handle towards the opening. As soon as the angle between the canvas and the opening decreases to<70°, дверь начнет автоматически закрываться.

On different closers, FOP is implemented in different ways. In some models - due to the folding lever. In others (including Palladium) - using an internal unregulated valve.

Please note that FOP cannot be disabled. This is usually not critical, since most people open their doors only 50-60 ° (if you want, check how you do it). But if you are firmly convinced that FOP will bother you, then you can buy door closers without this function, but with the same load. For example, models Palladium 1025 D, 1045 D (with FOP) correspond to models 1025 ST, 1045 ST (without FOP).

[How to adjust]

No way. This function is not adjustable or disabled.

7. IN CONCLUSION: SELECT CLOSER BY THE WEIGHT AND SIZE OF THE DOOR

Functions are functions, but the main criteria when choosing a closer are the weight and dimensions of the door leaf. If you choose a low-power device, the door will not slam, and the closer will quickly break or leak. And vice versa: put a closer with a load of 85-120 kg on a light canvas - the door will be harder to open. In addition, the load on the hinges will increase many times over.

Tags: door closer

Hinders door opening. It is necessary to make a truly titanic effort to move the door leaf from its place, and even more so to open it wide. What is the reason for this and is the door closer to blame?

Let's start with the terms. We have already written that immediately after installation, as well as when the season changes, the door closer needs adjustment. It is carried out using a simple screwdriver by tightening or loosening special adjusting screws brought out to the door closer body. However, this way you can only adjust closing force, that is, the force that the closer mechanism transfers to the canvas. Accordingly, in the process of adjustment, the speed of the door leaf will change in two segments of movement: from the opening angle to 18˚ and from 18˚ to the complete tight closing of the door.

But what about the effort that needs to be made to open the door? It should be noted that the expression “ opening force"We use metaphorically. By itself, this effort is regulated by a person: after all, it is the user, and not the door closer, who opens the door. In fact, if the door opens too tightly after installing a closer on it, you need to somehow adjust the sensitivity of the mechanism to the force exerted by a person on the door leaf when opening. There is no specific system for this adjustment. Moreover, if this adjustment is required, then the door closer is not working properly.

Looking for a reason

First, you need to figure out the reasons why the door with the closer opens too tightly.

Door closer class selection

The main and most common reason for tight opening lies in the fact that the power of the closer does not match the parameters of the door leaf (weight and width). Recall that the choice of a door closer should start with determining its class according to the European standard EN1154. This standard regulates the power of devices for automatic door closing and, according to this parameter, divides door closers into 7 classes: from EN1 to EN7. Each class has its own limit values ​​for the width of the door leaf and its weight.

It is very important to choose a door closer that matches the door exactly. Door closers have long ceased to be a gimmick, but until now, in many retail stores, sales assistants recommend buyers to purchase a door closer that is more powerful than actually required. They say it won't get any worse. Alas, it will! If we install a door closer on a door with a weight of 60 kg, designed to close a door with a weight of 120-160 kg, then we will get the very same problem: tight opening.

In order to understand why the “more powerful closer” will not effectively perform its functions on a door that is too easy for him, it is enough to imagine his mechanism. A powerful hardened steel spring that transmits its energy to the door and closes it is simply not able to adapt to the door at our will. That is why it is important to choose a door closer in strict accordance with the recommendations and the EN1154 standard.

Closer installation errors

Another common reason that a door can be difficult to open after a door closer has been installed is due to installation errors. They also happen quite often.

Each NORA-M door closer is completed with detailed installation instructions. There is also an article on our website that describes in detail all the stages of installing the door closer, with photographs of the process. Each manual contains a full-size template that attaches directly to the door leaf and allows you to accurately determine the mounting locations for the door closer body. However, installation errors still happen, and quite often. This can happen, for example, due to the fact that the paper template was exposed to moisture during storage or transportation and changed its size.

What to do?

If you managed to determine the cause of the tight opening of the door, then you need to eliminate it. If the matter is in the wrong selection of the door closer in terms of power, then there is only one way out - to change the device. The fact is that there are no technical possibilities to fix this error. The closer mechanism cannot be altered. Moreover, remember that all parts inside the device body are under pressure, and under no circumstances should it be disassembled! By the way, even if the opening force suits the user, a too powerful door closer on a light door will still work incorrectly, which can lead to its breakdown.

As for the incorrect installation, it can be corrected. This can lead to the appearance of unnecessary holes in the door leaf, which may be visible, but in this case, functionality is more important than aesthetics. The most effective way to adjust the force of opening a door with a closer is to move the device closer to the door hinges. This will increase the lever and thus make opening easier.

Support of NORA-M specialists

A door closer is a device whose action is aimed at quietly closing the door. The mechanism functions as follows: a physical force is applied to the door, and an impulse arises, which is transmitted to the device and acts in such a way that the door opens and closes without sudden movements and noise. If you want to create a door closer with your own hands, you will need parts, the purpose of which is not related to the principle of operation of the door.

It looks like a door closer

Choosing the right door closer

Before choosing a door mechanism, you need to familiarize yourself with its functions. The principle of the door closer is to close the door quietly and smoothly. This is reflected in the following factors:

Detailed instructions for installing a door closer

Step-by-step instruction

If there is no model in the kit, then the technical passport indicates the exact dimensions and measurements by which the door closer can be mounted.

Door closer adjustment

After installing the closer in the door, a check is needed. If the door opens tightly, closes or slams, you can adjust the door closer with your own hands.


There are 2 screws on the door closer. They take over the main functions of the mechanism. 1 screw - speed when closing the door, 2 - adjusting the tightness of closing the door and its adherence to the frame. If the door slams, you need to adjust the second screw. It must be twisted slowly (a little - half a turn), then check the closing of the door. This should be done until the door stops slamming.

Door closer adjustment options

To close the door a little slower, you need to turn the screw clockwise so that the speed is counterclockwise.

Closer with more than 2 screws

There are door closers with more than 2 adjustment screws. In this case, the purpose of each screw is indicated in the technical passport. In addition to the standard door adjustment screws (speed and pop), there are also screws that are responsible for other functions of the mechanism.


One screw serves as a door brake when opening. That is, it will not work to open the doors with a sharp movement. The second screw leaves the doors open. That is, if the door is wide open, then it will remain in this position and will not close.
