IS IT TIME TO REPLACE THE DOOR CLOSER?
If your door closer is slamming the door and cannot be adjusted to do otherwise, either the fluid has leaked out or the valve seals are worn out. In either case, your best option is to replace it.
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.
