Hager Hinge 127931210D Full Mortise Hinge 3.5x3.5 Black Nickel

Product Description

The HAGER HINGE 127931210D is a full mortise, five knuckle, plain bearing door hinge finished in black nickel. Standard weight construction makes it suitable for interior and light-duty exterior door applications where a clean, finished appearance is required. The plain bearing design provides smooth, reliable door swing without the need for lubrication under normal use. At 3.5 inches by 3.5 inches, it fits standard residential and light commercial door preps. Installation is performed by a carpenter, general contractor, or finish hardware technician as part of a door and frame assembly.

This hinge is intended for full mortise door installations where both the door and the frame have machined pockets to receive the hinge leaves flush. The black nickel finish suits applications where a dark, matte-toned hardware aesthetic is specified. Sold individually, it is appropriate for new construction and renovation projects requiring standard-weight hinge hardware in a five knuckle profile.

Installation Notes

Full mortise hinges are installed by finish carpenters or door hardware technicians using a chisel or router to cut hinge mortises into the door edge and frame jamb. Power down any access control or electric strike hardware associated with the door before beginning work. Verify mortise depth and leaf alignment before fastening to avoid hinge bind or misalignment. Follow applicable building and fire code requirements for hinge quantity and placement on rated door assemblies.
