Hager Hinge 127941215 Full Mortise Plain Bearing Hinge 4.5in Satin

Product Description

The HAGER HINGE 127941215 is a full mortise, five-knuckle, plain bearing door hinge with a satin nickel finish, designed for standard-weight door applications in commercial and residential construction. The hinge measures 4.5 inches x 4.5 inches and is sold individually. Plain bearing construction suits standard-frequency swing doors where heavy-duty or high-cycle ball bearing hinges are not required. This hinge is installed by finish carpenters, general contractors, and door hardware specialists as part of new construction or replacement door hardware projects.

This hinge is suited for interior and exterior door installations where a full mortise mount is specified. Full mortise hinges are recessed into both the door edge and the door frame, producing a flush, clean profile when installed. The satin nickel finish integrates with a wide range of commercial and residential door hardware finishes. Typical applications include office doors, corridor doors, and residential entry or passage doors requiring a standard-weight five-knuckle hinge in a 4.5-inch leaf size.

Installation Notes

Installation is performed by qualified finish carpenters or door hardware technicians. Mortise the hinge leaf recesses into both the door stile and the door frame jamb before securing with fasteners. Verify door weight and swing frequency against hinge load rating prior to installation to confirm plain bearing construction is appropriate for the application. Follow applicable building code requirements for door hardware installation in the jurisdiction of the project.
