Hager Hinge BB1279410D Full Mortise Ball Bearing Hinge

Product Description

The HAGER HINGE BB1279410D is a full mortise, standard weight ball bearing hinge finished in black nickel. It is designed for use on interior and exterior doors where a clean, recessed installation is required. The ball bearing design reduces friction and supports smooth, consistent door operation over the service life of the hinge. At 4 inches x 4 inches, this hinge suits standard commercial and residential door applications. Installation is performed by carpenters, finish carpenters, and door hardware technicians as part of new construction or replacement work.

This hinge is suited for full mortise door applications where the hinge leaf is recessed flush into both the door edge and the door frame. The black nickel finish makes it appropriate for projects specifying a dark hardware finish. It is sold individually and is well-suited for commercial light-duty and residential door installations where a standard weight hinge meets the load requirement.

Installation Notes

Installation is typically performed by a licensed carpenter or door hardware installer. Power down any associated access control or electric strike hardware before beginning door removal. A sharp mortise chisel and router template are standard tools for achieving a flush, properly sized hinge mortise. Follow applicable local building codes for door hardware requirements on fire-rated or egress door assemblies.
