Hager Hinge 127941226 Full Mortise Hinge 4.5x4.5 Bright Chrome

Product Description

The HAGER HINGE 127941226 is a full mortise, five knuckle plain bearing hinge finished in bright chrome. Designed for standard-weight door applications, it mounts flush within a routed mortise pocket in both the door edge and the door frame, providing a clean, concealed look once installed. The hinge measures 4.5 inches by 4.5 inches, making it appropriate for medium to heavy interior and light commercial door assemblies. At 1.13 pounds per unit, the standard weight construction suits typical passage doors where heavy-duty ball bearing hardware is not required. Door hardware installers and general contractors are the primary trades that specify and install this hinge type.

This hinge is used in residential and light commercial new construction or renovation projects where full mortise installation is specified. Full mortise hinges are standard on wood and hollow metal door applications where the hinge leaf must sit flush with the door edge and frame face. The five knuckle configuration provides consistent pivot alignment and smooth, quiet operation. The bright chrome finish suits interior environments where polished hardware is specified to match locksets, closers, and other door hardware trim.

Installation Notes

Full mortise hinges are installed by door hardware technicians, finish carpenters, or general contractors following ANSI and BHMA standards for door hardware. The mortise pocket must be accurately routed to the correct depth in both the door edge and the frame jamb before the hinge leaf is seated and fastened. Ensure the door is properly blocked and supported before removing an existing hinge during replacement work. Verify that the door weight and frequency of use are consistent with a plain bearing, standard-weight specification before installation.
