Hager Hinge 1279426D Full Mortise Plain Bearing Hinge 4x4 Satin Chrome

Product Description

The HAGER HINGE 1279426D is a full mortise, five knuckle, plain bearing standard weight hinge with a satin chrome finish. Designed for commercial and residential door applications, this hinge mounts flush within a mortised cutout on both the door and frame, providing a clean, low-profile installation. The plain bearing design supports consistent door swing under moderate traffic conditions. At 4 inches x 4 inches, this hinge suits a wide range of interior door weights and sizes. Installation is typically performed by a licensed carpenter, door hardware specialist, or general contractor as part of new construction or door replacement work.

This hinge is suited for standard-weight interior doors in commercial offices, institutional facilities, and residential applications. The full mortise configuration requires routed pockets in both the door edge and the door frame, making it a common choice for pre-hung door assemblies and field replacements on hollow-core or solid-core wood doors. The satin chrome finish coordinates with contemporary and transitional hardware sets. Sold individually, it can be ordered in case quantities of 48 units for larger projects.

Installation Notes

Installation is performed by a qualified carpenter or door hardware technician using standard mortising tools or a hinge template router jig. Ensure the door is fully supported and stationary before removing any existing hardware. Mortise pockets in both the door edge and frame must be sized precisely to the leaf dimensions to ensure flush seating and proper door alignment. Follow applicable building code requirements for hinge quantity and placement based on door height and weight.
