Choice of door closer with hold-open position
A door closer is a mechanical design that is designed to automatically close open doors. The door closer device provides for a smooth bringing of the door to the "closed" position and ensures its tight pressing against the frame contour. However, not only standard door closer models are presented on the modern market. For example, there are devices that are capable of locking the door in the "open" position. What is a hold-open door closer? How to choose the right mechanism of this type. How can you install it yourself? Look for answers to these questions in our material.
Peculiarities
To begin with, it should be noted that door closers are installed on those doors that are equipped with access control. Also, these devices are suitable for fire and evacuation ceilings. If we talk about mechanisms that have the function of fixing the door open, then it should be noted that such structures are most often used where it is necessary to ensure greater traffic of people (for example, shops and boutiques, shopping centers and cinemas, schools, universities and offices). If there is such a closer on the doors leading to public premises, then the passage of visitors will be carried out without delays in opening and closing.
The custom-designed door can be opened just once, then it will stay that way until the end of the day. In addition, such a door lock is useful for organizations and companies involved in trade, for example, shipping and unloading goods. It will help solve a large number of problems and will allow you to enter or leave the premises, even if your hands are full.
How to choose?
There are several mandatory characteristics and criteria that you must pay attention to when choosing a door closer. So, when choosing and buying a device, you should take into account the weight and width of the door leaf. Obviously, the wider, heavier and more massive the door is, the more difficult it is to hold it, respectively, the more powerful a door closer will be needed. Do not neglect this characteristic and do not hope for an accident - the manufacturer carefully checks the process of the door closer and the most suitable door parameters for it. An inattentive attitude to this criterion can lead not only to a breakdown of the door closer itself, but also to disruption of the door.
An equally important indicator is the local climate and environmental conditions. It is important to understand in what temperature ranges the device will function. So, on the construction market there are special thermostable models that can work in a wide temperature range. Also, in order for the door closer to fully and correctly function in the event of unexpected and sudden temperature changes, it is recommended to purchase and install a special thermal shutter, which is a special device for internal valves.
When buying a mechanism, you must also carefully read the instruction manual. It is in it that you can find out all the necessary information about the manufacturer and make sure that you are purchasing a really high-quality product. Also, do not hesitate to ask the seller for a license and quality marks. The closer you purchase must comply with the European standard EN 1154 or the domestic GOST R.
How to install?
In order to easily install a do-it-yourself street closer that responds to door opening, you must use one of four possible methods:
- overhead;
- installation in the frame;
- installation in the floor;
- installation in the door.
Moving on to the direct installation of the latch, which is able to hold the door in the open position, you should make sure that the rod is in the installed state. Then you need to check that the center screw is tight (if not, then tighten it using a six-sided wrench). The next step is to move the vertical relative to the horizontal arm until the valve is blocked by a spring-loaded ball.
After that, it is necessary to unscrew the central screw 2 turns (so that the vertical arm moves independently of the horizontal one). Now it's time to install the rod together with the closer. When this procedure is done, open the door to the angle in which it will be held by the closer in the open position and hold it. Retighten the center screw.
The main part of the work is over, the door is locked in the "open" position. Then unlock the door to test the door closer (for this you need to pull it). Further, the closer itself will close the door to the end. Thus, we are convinced that installing a door closer that is able to hold the door in the open position is a process that almost everyone can carry out. The main thing is to strictly follow the instructions of the instructions. It is also important to choose the right design, and for this it is necessary to take into account all the advice of specialists and rely on the instructions listed above.
