Product Description

The HAGER HINGE BB12794124 is a full mortise, standard weight ball bearing hinge finished in satin brass. It is designed for interior and exterior door applications where a clean, flush-mounted hinge is required. The ball bearing construction reduces friction and wear over repeated cycles, making it suitable for commercial and residential door installations. At 4.5 inches by 4.5 inches, it fits standard full-size door frames and is installed by carpenters, door hardware specialists, and general contractors as part of new construction or retrofit projects.

This hinge is used in full mortise door installations, where both the door and the frame are routed to accept the hinge leaves flush with the surface. It is appropriate for standard weight doors in commercial and residential settings. The satin brass finish suits both architectural and functional applications. It is sold individually and is compatible with standard door prep dimensions used across the industry.
