Pemko 145D72 72" 6' x 4" x 7/8" Interlocking Threshold Dark Bronze Anodized Aluminum Finish

This interlocking residential threshold creates a weatherproof barrier at door openings where water infiltration is a concern. The 145 series design features a water return channel that directs moisture away from the building interior. Pemko engineered this threshold with a 4" x 7/8" profile that accommodates standard residential door frames while providing reliable weather sealing performance.

The dark bronze anodized aluminum finish resists corrosion and matches commercial door hardware. The interlocking design works with compatible door bottom seals to form a continuous weather barrier. Installation hardware is included with the 72-inch length threshold. The fire-rated construction makes this suitable for openings requiring both weather protection and fire door compliance.

This threshold meets UL 10C positive pressure and UL 4L10 listing requirements for fire-rated door assemblies. For fire door inspection requirements, see UL 10C fire-rated door assemblies. For broader code context on egress requirements, see NFPA 101 Life Safety Code.
