Hager Hinge 127941210DNRP Mortise Hinge 4.5x4.5 Black Nickel

Product Description

The HAGER HINGE 127941210DNRP is a full mortise, five knuckle, plain bearing hinge in a standard weight configuration, finished in black nickel with a non-removable pin. Measuring 4.5 inches by 4.5 inches, this hinge is designed for mortise installation into door edges and corresponding frame cutouts, providing a flush, clean fit when properly routed. The non-removable pin design adds a layer of security by preventing pin extraction from the hinge barrel on the exterior side of the door. This hinge is typically installed by carpenters, door hardware specialists, or general contractors during new construction or door hardware retrofit projects.

This hinge suits interior and exterior door applications where a standard weight five knuckle mortise hinge is specified. The black nickel finish makes it appropriate for commercial or residential installations where consistent finish matching is required across door hardware sets. Sold individually, it is commonly specified in commercial door openings, office environments, and residential entry or passage door projects where a non-removable pin security hinge is called for by the hardware schedule or project spec.

Installation Notes

Full mortise hinges require precise router or chisel work to cut matching mortises in the door edge and door frame jamb before installation. Power down any electric hardware or access control components associated with the door opening before beginning work. Follow applicable building codes and door hardware specifications, including ANSI and BHMA standards where referenced in the project documents. Verify hinge count and placement per door weight and height requirements before final fastening.
