The Door and Hardware Institute (DHI)

Through DHI we have on staff Architectural Hardware Consultants (AHCs) who are trained to recognize the requirements for door openings in all types of public, commercial, industrial and institutional buildings.

Based on NFPA80, Standard for Fire Doors and Other Opening Protectives, we have on staff a Fire Door Inspector (FDAI) certified to inspect your fire-rated door assemblies for compliance.
