Hager Hinge 1279412PNRP Full Mortise Plain Bearing Hinge

Product Description

The HAGER HINGE 1279412PNRP is a full mortise, five knuckle, plain bearing hinge designed for standard-weight door applications. Measuring 4.5 inches by 4.5 inches, it features a non-removable pin for added security and arrives with a prime coat finish ready for field painting. The plain bearing construction suits interior and light commercial doors where heavy-duty ball bearings are not required. This hinge is installed by door hardware professionals, carpenters, and general contractors as part of a complete door prep and hang sequence. The prime coat finish allows the installer to match the final paint or finish to the surrounding frame and hardware.

This hinge is suited for standard-weight interior and exterior door applications where a full mortise, five knuckle configuration is specified. The non-removable pin design prevents the hinge pin from being driven out from the exterior side of the door, making it appropriate for outswing door installations where security is a consideration. It ships as a single unit and is commonly specified on commercial and light institutional projects alongside matching door hardware sets.

Compatibility

Installation Notes

Installation is performed by a qualified door hardware installer or carpenter. Mortise the door edge and frame jamb to the exact leaf dimensions before fastening to ensure a flush fit and proper door swing. Follow applicable building code requirements for hinge quantity per door leaf based on door height and weight. Verify that the non-removable pin orientation is positioned on the correct side of the door prior to final installation, as it cannot be repositioned without removing the hinge.
