Pemko 170A36 36" 3' x 4" x 1/2" Saddle Threshold Mill Finish Aluminum Finish

The 170A36 creates smooth floor transitions while meeting accessibility requirements at commercial doorways. This flat saddle threshold handles the height differential between flooring materials while providing weather protection and thermal insulation. Pemko designed this 36-inch threshold to solve ADA compliance issues and fire door assembly requirements in one installation.

The fluted aluminum surface provides slip resistance and durability in high-traffic areas. Mill finish anodized construction resists corrosion and wear. The 1/2-inch height profile keeps transitions within ADA slope limits while the 4-inch width spans typical door frame gaps.

This threshold meets UL 10C positive pressure requirements for fire door assemblies and ANSI/BHMA A156.21 threshold standards. ADA compliance per ANSI/BHMA A117.1 ensures accessibility code requirements are satisfied.

Fire door installations require UL 10C testing to maintain assembly ratings through positive pressure conditions. For broader accessibility context in commercial buildings, NFPA 101 Life Safety Code establishes egress requirements that work alongside threshold compliance.
