22" x 36" - Fire Rated Un-Insulated Access Door with Plaster Flange - Cendrex
The PFN-PLY access door is not insulated and can only be used on fire rated walls, specifically those made of plaster. Once covered with plaster, the 2 3/4" lath flange will disappear, leaving only the door panel visible. As per UL standards, once the installation is complete and the provided springs installed, this door will be self closing and self locking. It should not be used in situations where protection against temperature elevation is required. The largest fire rated PFN-PLY door available is: (36" x 36").
