Can a door stop go on a fire door?

Only where the door's listing and the code that apply allow it, and the stop does not get in the way of the door closing and latching. A fire door has to close and latch by itself, so a stop must not hold it open. Where a fire door may be held open, it takes a listed hold open device that releases it through the detection or alarm system the code requires, such as an electromagnetic door holder . See NFPA 80 , and ask your authority having jurisdiction.

Door Stops and Silencers

A door stop keeps an opening door from hitting the wall, a lock or a fixture, and from straining its hinges. A wall stop, or wall bumper, mounts on the wall where the door or its hardware would hit and takes the blow on a rubber bumper. A concave bumper is hollowed to receive a lock with a projecting button, so the button is not damaged. A floor stop mounts on the floor in the door's swing: a low dome stop suits a door without a threshold, and a taller one a door with a threshold or a deep undercut. Place a floor stop where it will not trip anyone.

Door silencers are small rubber bumpers set into the stop of the frame. They cushion the door as it closes, cut the noise and stop the door rattling against its latch. Silencers for hollow metal frames press into drilled holes, and a single door usually takes three on the strike side; follow the maker's template for the number and spacing. Stops and silencers are graded under ANSI/BHMA A156.16. For stops that mount at the top of the door instead, see overhead door stops and holders.
