Door Closers — MAB564N

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), control over the rate of closing, safety, durability, risk of vandalism, anti-ligature and aesthetics.
