Hager Hinge 1279410D Full Mortise Plain Bearing Hinge Black Nickel

Product Description

The HAGER HINGE 1279410D is a standard-weight, full mortise, five-knuckle hinge with a plain bearing design and a Black Nickel finish. It measures 4 inches by 4 inches and is sold as an individual unit. This hinge is designed for mortise installation on interior or exterior doors where a clean, flush-mounted pivot point is required. The five-knuckle construction distributes load across more bearing surface than a three-knuckle design, making it a dependable choice for standard door applications. Installation is handled by finish carpenters, commercial door installers, and experienced general contractors working on door hardware replacement or new construction.

The 1279410D is suited for standard-weight door applications in residential and light commercial settings. The full mortise configuration requires a routed mortise pocket in both the door edge and the door frame, making it appropriate for pre-hung door assemblies or site-mortised installations. The Black Nickel finish is compatible with coordinating door hardware sets in that finish family. This hinge is sold individually, allowing for single-unit replacement or precise quantity ordering for multi-door projects.

Compatibility

Installation Notes

Installation is typically performed by finish carpenters or commercial door hardware installers. Power down any electric strike or access control hardware associated with the door assembly before beginning work. A mortise router template and sharp chisels are standard tools for achieving a clean mortise pocket on both the door edge and the frame. Verify that the hinge leaf sits fully flush before fastening to prevent binding during door operation.
