Product Description
The HAGER HINGE BB127941210A is a full mortise, standard weight ball bearing hinge finished in dark bronze. It measures 4.5 inches by 4.5 inches and is designed for commercial and residential door applications where smooth, consistent swing performance is required. The ball bearing design reduces friction and wear over the life of the door, making it appropriate for moderate-traffic entryways. This hinge is installed by carpenters, door hardware specialists, and general contractors during new construction or door replacement projects.
This hinge suits standard interior and exterior door frames requiring a full mortise installation. The dark bronze finish integrates with common architectural hardware finishes used in commercial office, hospitality, and residential construction. It is sold individually and is also available in case quantities of 48 units for larger projects.

Installation Notes
Installation is performed by a qualified carpenter or door hardware installer using a mortise chisel, router, and appropriate fasteners. Power down any electronic access control or electric strike associated with the door before beginning work. Ensure mortise pocket dimensions match hinge leaf size precisely to maintain proper door alignment and prevent binding. Follow applicable building codes for door hardware installation in your jurisdiction.
