Hager Hinge 1279412L1 Full Mortise Hinge 4.5x4.5 Flat Black

Product Description

The HAGER HINGE 1279412L1 is a full mortise, five knuckle, plain bearing door hinge in a flat black finish. Designed to standard weight specifications, this hinge measures 4.5 inches x 4.5 inches and is built for commercial and residential door applications where a clean, recessed installation is required. The plain bearing design suits standard-traffic doors, and the flat black finish provides a consistent, low-sheen appearance. Licensed carpenters, general contractors, and door hardware installers work with this type of hinge on interior and exterior mortise door assemblies. The five knuckle barrel construction distributes load across the door leaf and frame evenly.

This hinge is suited for full mortise installation on standard-weight door applications. Full mortise hinges are routed flush into both the door edge and the door frame, producing a clean profile with no exposed barrel overhang. Typical installations include commercial office doors, residential interior doors, and light commercial entryways where a flat black hardware finish is specified. Each unit is sold individually, with case quantities of 48 available for larger projects or contractors stocking for multiple openings.

Installation Notes

Installation is performed by licensed carpenters or door hardware specialists. Power down any electrified door hardware associated with the opening before beginning work. A router or sharp mortise chisel is required to prepare the door edge and frame leaf pockets to proper depth; a shallow mortise will prevent the door from closing flush. Follow local building codes and manufacturer door specifications for hinge quantity per door leaf based on door height and weight.
