Emtek 91013US3 Square Steel Hinge Pair 3.5x3.5 Polished Brass

Product Description

The EMTEK 91013US3 is a pair of square residential duty hinges finished in polished brass with a lifetime coating. Each hinge measures 3.5 inches by 3.5 inches and is constructed from steel for reliable, everyday door operation. Sold as a pair, these hinges are designed for interior and light-duty exterior residential door installations where a clean, square-corner profile is specified. The polished brass lifetime finish resists tarnishing and wear under normal residential use conditions, reducing long-term maintenance for the installer or homeowner.

These hinges are suited for standard residential door applications including interior passage doors, closet doors, and bedroom or bathroom entries. The square-corner design is compatible with door frames and door blanks routed for full-mortise square-corner hinge prep. The 3.5-inch leaf size is the most common specification for residential interior doors in both new construction and retrofit replacement work. Installation is straightforward for carpenters, door hardware specialists, and experienced finish trades.

Installation Notes

Installation is typically performed by a finish carpenter or door hardware installer. Remove the door from the frame and ensure power to any associated electric strike or access hardware is off before service. Mortise depth and leaf seating should be verified before fastening to prevent binding or misalignment. Follow applicable local building codes for door hardware requirements in egress or fire-rated door assemblies.
