fire door Modifications
Nov 20, 2018

NFPA 80 includes guidelines concerning field modifications of listed hardware, including frames, builder's hardware, doors, thresholds etc. The growing field of access control and electronic entry systems has resulted in some fire doors being field modified without proper listing agency approval. Field modifications of fire listed assemblies must either be inspected by a listing agency representative, or the modification must be performed by personnel certified to perform such work.
