Best 711422100 Full Mortise Concealed Hinge Steel Primed

Product Description

The BEST 711422100 is a full mortise concealed hinge designed for commercial and institutional door applications where a clean, low-profile installation is required. Built from steel with a primed finish, this hinge mounts flush within routed mortises on both the door and frame leaves, keeping the hinge body hidden when the door is closed. At 4 inches overall width with a 3-knuckle barrel, it provides stable pivot support for standard-weight doors. Licensed door hardware technicians and commercial construction crews are the primary installers. The primed finish accepts field painting to match the surrounding frame or door finish.

This hinge is suited for commercial door openings where a mortise-style installation is specified. It is appropriate for use in assemblies requiring compliance with ANSI K81071F and NFPA 80 fire-rated door standards. The steel construction and primed finish make it a common choice for hollow metal door and frame assemblies in commercial, institutional, and industrial settings where door hardware must meet fire-door labeling requirements.

Installation Notes

Installation is performed by licensed door hardware technicians or commercial carpenters familiar with fire-rated door assembly requirements. Power down any associated electric hardware and follow NFPA 80 guidelines when servicing fire-rated door assemblies. Mortise pockets in both the door and frame must be routed to exact depth before installation to ensure proper hinge seating and door alignment. Verify that the completed assembly meets all applicable fire-door labeling requirements before returning the door to service.
