What might cause a door to slam shut?
This particular door slammed shut upon closing, making a loud noise that scared customers and led to hazardous conditions.
When a glass door slams with such force, they could shatter! Usually, the reason for this is a malfunctioning door closer, which is responsible for the speed and strength of the shutting.
Here, our technicians replaced the worn door closer with a new one, thereby greatly improving the door speed.
How do commercial door closers work?
Commercial door closers make doors shut smoothly behind you without having to physically close them yourself.
A newly installed door closer may cause a user to feel some resistance as they begin to open the door, giving them a sense of how heavy the door is. This “heaviness” will subside after regular use.
Finally, when a user lets go of the door, a spring in the door closer forces the mechanism’s arm to close gently until the door returns to the frame.
