Hager Hinge BB174131215EA Full Mortise Ball Bearing Hinge

Product Description

The HAGER HINGE BB174131215EA is a full mortise, ball bearing residential-weight door hinge finished in satin nickel. It measures 3.5 inches by 3.5 inches with square corners, making it a standard fit for interior and light-duty exterior residential door applications. Ball bearing construction reduces friction and wear over the life of the hinge, supporting smooth, consistent door operation. This hinge is installed by carpenters, finish contractors, and door hardware technicians as part of new construction or replacement door hardware projects. It ships and is sold as an individual unit (EA), though it must be ordered in multiples of 2.

This hinge is suited for residential-weight door applications where a full mortise installation is required. Full mortise hinges are set into routed pockets in both the door edge and the door frame, providing a flush, clean finish. The satin nickel finish coordinates with a wide range of residential hardware finishes. Typical applications include interior passage doors, bedroom doors, and light-duty closet doors in residential construction or renovation.

Installation Notes

Installation is typically performed by carpenters or finish hardware technicians using a chisel or router to prepare mortise pockets in the door edge and frame jamb. Ensure the door is properly supported and the hinge leaves are fully seated and flush before fastening. Follow door manufacturer specifications for hinge quantity per door based on door height and weight. Verify all fasteners are properly set to avoid door misalignment.
