Hager Hinge BB1279426D Full Mortise Ball Bearing Hinge

Product Description

The HAGER HINGE BB1279426D is a full mortise, standard weight ball bearing hinge finished in satin chrome. It is designed for interior and exterior door applications where smooth, consistent swing performance is required. The ball bearing mechanism reduces friction at the pivot point, extending service life under repeated use. At 4 inches x 4 inches, this hinge suits standard commercial and residential door frames. Sold individually, it is typically installed by carpenters, finish contractors, and door hardware specialists on wood or hollow metal door assemblies.

This hinge is suited for full mortise door installations, meaning both the door edge and the frame must be routed to accept the hinge leaf. The satin chrome finish provides a neutral, low-sheen appearance compatible with a wide range of door hardware finishes. The standard weight designation makes it appropriate for typical passage doors rather than heavy-duty or high-frequency applications. Installation is common in light commercial and residential construction where door hardware must meet consistent performance standards.

Installation Notes

Installation is performed by qualified carpenters or door hardware technicians using a router or chisels to cut mortises in both the door edge and the frame. Ensure the mortise depth matches the hinge leaf thickness to achieve a flush fit before fastening. Verify door weight and frequency of use against the standard weight rating before installation. Follow applicable building codes for door hardware installation in commercial occupancies.
