FREQUENTLY ASKED QUESTIONS ABOUT DOOR CLOSERS
An automatic door closer, more often called a “door opener”, opens the door itself, typically under the control of a push button, motion detector or other device, and then closes it as well, employing a motion or proximity detector to determine when it is safe to close the door.
There are three different types of door closers: Regular Arm, Parallel Arm and Top Jamb Mount. Each of these function in a similar way, but they are installed on different sides of the door
A door closer is a mechanical device designed to close a door slowly but firmly enough to latch. It accomplishes this by using spring tension modulated by hydraulic fluid. … Swing speed adjustment controls how fast the door closes from fully open to within about five degrees of closed.1
How do you determine handing for a door closer?
Push the door away from you as if you are going to walk thru the opening. If the hinges are on your right, it is a RH door.
If you are on the pull side (hinge side) of the door, and the hinges are on your right, it is a LH door.
Just stick a few small felt pads along the edge of the doorframe: Position a pad at the top and bottom of the frame, along with two more pads at the top and bottom of the strike plate. The pads provide just enough soft cushioning to slow down the door as it closes, preventing a slam.
A door experiencing so much traffic requires a long-lasting mechanism, and Grade 1 door closers last up to seven years before requiring replacement.
If the problem is a damaged arm or adjusting screw which can be repaired, then do that. If the door closer does not respond to therapy (the appropriate adjustments), it is likely internally damage and needs to be replaced.
The purpose of the closer is to ensure that the door is closed during a fire or to prevent someone getting into your home. When it is failing to do its job it’s time for a new one! Equally, if the door is slamming – It is possible that the hydraulic fluid or oil has leaked out or the valve seals are worn.
“Fire door – keep locked” doors do not have door closers to ensure they remain closed in a fire situation, relying on the lock alone. Any fire door will have a minimum of three hinges. Intumescent may be required, so it is important to check certification.
Door closers with a regular arm will be mounted on the pull side of the opening. The closer body is mounted to the top of the door and the closer arm is attached to the face of the frame head.
