A door closer is a mechanical hydraulic device that closes a door. They come in a variety of styles to suit both your functional and aesthetic preferences. Options include. Rack and pinion door closers, floor springs (door closer concealed in the floor), and industrial door closers.
A door closer is defined as any mechanical device that closes a door in a controlled manner, preventing it from slamming, in general after someone opens it or after it was automatically opened. The force used to open the door is stored in some type of spring and when released this energy is then used to return the door to a closed position. Door closers can be linked to a building’s fire alarm system. Where doors need to be held open for the majority of the time they are held back with an electromagnetic device. When the fire alarm is triggered it cuts power to the electromagnetic hold-open device allowing the doors to close. These hold-open devices can be separated from the door closer or part of its design
What is the purpose of door closers?
A door closer will ensure that the door returns to the closed position after the opening, allowing the locking element to engage and secure the door. Doors using maglocks, electric strikes, or electric locks would all require a controlled door-closing device to be fitted to provide secure closing
What are the advantages of using a closer?
A door closer will ensure that your building or suite entrance door has closed securely after someone passes through it. This prevents your property from being left vulnerable to thieves and prevents unauthorized access. Having the correct door closer is especially important on doors with access control.
