Listed Door Closing Device

Fire-rated openings are used to compartmentalize a building or space to prevent the spread of flame, smoke and toxic gases. The 2019 edition of NFPA 80, Standard for Fire Doors and Other Opening Protectives, establishes the criteria that fire-rated doors and frames must meet.

NFPA 80 requires side hinged and pivoted fire-rated doors and frames to be tested in accordance with established testing methods and procedures listed in NFPA 252, Standard Methods of Fire Test of Door Assemblies.
