According to NFPA-80, fire-rated doors require to have a self-closing mechanism. In the meantime, ADA sets specific guidelines for door clearance. On the basis of ADA Protruding Objects Chapter 307.4 Vertical Clearance, “Headroom clearance of at least 80” high is required along all circulation paths (except at doors and doorways where a 78” minimum clearance is permitted to accommodate door stops and closers.” Therefore in order to meet this ADA specification, no door closer is installed within the 78” minimum clearance space.

Fire Door Clearance Requirements

Commercial fire-rated doors are typically 80″ or 84” high. With an 80” door, it is impossible to install a top door closer and meet the 78” minimum clearance requirement. Therefore one’s choice is to either use a bigger, more expensive 84” fire resistance door or use a shorter opening with a spring hinge. Sadly conventional spring hinges will undoubtedly slam loudly and hazardously. In the case of an 84” door, you will only have 6” of space to install a self closing device and its swing arm; that said, a mere 6” limits your traditional door closer selections.
