A door closer is a mechanical device that closes a door, in general after someone opens it, or after it was automatically opened. Choosing a door closer can involve the consideration of a variety of criteria. In addition to the closer's performance in fire situations, other criteria may include resistance to opening forces (for use by disabled or infirm) as well as health, safety, durability, risk of vandalism/ligature and aesthetics.

An exit device is a mechanical lock operated from the inside of an outward swing door through the use of a crossbar or push rail extending at least halfway across the width of the door. An exit device must always release the door, allowing exit without prior knowledge of operation. Any horizontal force on the cross bar or push rail will release the door.
