Hager Hinge 1279426 Full Mortise Hinge 4 X 4 Bright Chrome

Product Description

The HAGER HINGE 1279426 is a full mortise, five knuckle, plain bearing door hinge in a bright chrome finish, designed for standard-weight door applications. Measuring 4 inches x 4 inches, this hinge is mortised into both the door edge and the frame to sit flush with the surface, producing a clean, professional installation. Plain bearing construction is appropriate for standard-frequency, standard-weight door cycles. This hinge is sold individually and is a common specification item for commercial and residential door hardware projects installed by carpenters, door and hardware technicians, and general contractors.

This hinge suits interior and light-duty exterior door applications where a standard-weight, full mortise hinge is specified. It is appropriate for hollow metal frames, wood frames, and wood doors in both residential and light commercial settings. The bright chrome finish coordinates with standard chrome door hardware trim. Sold as a single unit, it is typically specified in sets of two or three per door depending on door height and weight requirements.

Installation Notes

Installation is performed by qualified carpenters or door hardware technicians using a chisel, router, or mortising jig to cut the hinge pocket in both the door edge and the door frame. Ensure the door is properly supported and the opening is plumb and square before mortising. Fasteners should be driven straight to avoid stripping and ensure full thread engagement. Consult local building codes for hinge quantity and placement requirements based on door height and weight.
