Best 711067282 Full Mortise Concealed Hinge Steel Primed

Product Description

The BEST 711067282 is a full mortise concealed hinge designed for commercial and institutional door applications where a clean, flush-mounted appearance is required. Built from steel with a primed gray finish, this hinge seats fully into routed mortises on both the door edge and the frame, leaving no exposed hinge barrel on the face of the door. It features a 4-inch overall width, 5 knuckles, 2 ball bearings for smooth operation, and a non-removable stainless steel pin for added security. Licensed contractors and door hardware installers specify this type of hinge for hollow metal and wood door assemblies in commercial builds.

This hinge is suited for full mortise installations in commercial, institutional, and light industrial door frames. The primed gray finish makes it ready to accept field-applied paint, which is standard practice on hollow metal door and frame assemblies. The non-removable pin design meets security requirements commonly called out in commercial door hardware schedules. It is appropriate for use on interior and exterior doors where a mortise hinge is specified per the project hardware set.

Installation Notes

Installation requires a licensed door hardware installer or finish carpenter familiar with commercial door hardware schedules. Power down any electrified hardware tied to the door assembly before beginning work, and verify that mortise dimensions are routed to the correct depth before seating the hinge. Follow the applicable project hardware schedule and local building code requirements for fastener type and count. Do not force the hinge leaves into undersized mortises, as this can cause misalignment and binding.
