Hager Hinge BB12794P Full Mortise Ball Bearing Hinge 4x4

Product Description

The HAGER HINGE BB12794P is a full mortise, standard weight ball bearing hinge finished in prime coat, designed for commercial and residential door applications requiring smooth, low-friction operation. Measuring 4 inches by 4 inches, this hinge installs directly into mortised door and frame cutouts for a flush, clean fit. The ball bearing mechanism reduces wear at the pivot point, making it well suited for moderate-traffic doors where reliable performance and long service life are required. The prime coat finish accepts paint, allowing for field finishing to match surrounding hardware or door frame color. Sold individually, it fits standard door hardware installation workflows used by carpenters, locksmiths, and general contractors.

This hinge is appropriate for interior and exterior door installations in residential and light commercial construction. It is used in new construction and retrofit projects where full mortise hinges are specified by the door hardware schedule or architectural plans. The prime coat finish is commonly selected when the finish will be painted on-site to match door or frame color. Standard weight construction suits doors of moderate weight and frequency of use, making this hinge a practical choice for office, utility, and residential door openings.

Installation Notes

Installation is typically performed by a carpenter, door hardware installer, or licensed locksmith. Power down any access control or electric hardware connected to the door frame before service. Mortise cutouts in both the door and frame must be accurately sized and squared to achieve a flush, binding-free fit. Follow local building codes and the door manufacturer's hardware specifications when selecting hinge quantity and placement.
