Hager Hinge BB12794123 Full Mortise Ball Bearing Hinge

Product Description

The HAGER HINGE BB12794123 is a full mortise, standard weight ball bearing hinge finished in bright brass. It is designed for commercial and residential door applications where smooth, low-friction operation and long service life are required. The hinge measures 4.5 inches by 4.5 inches and weighs 1.15 pounds per unit. Ball bearing construction reduces wear at the pivot point, making this hinge well-suited for doors that see frequent use. Licensed contractors, finish carpenters, and door hardware installers are the typical trades who source and install this component.

This hinge is used in full mortise door applications, meaning both the door edge and the door frame receive routed pockets that accept the hinge leaves flush. It is appropriate for standard weight door assemblies in residential and light commercial settings. The bright brass finish suits interior and select exterior installations where a polished brass aesthetic is specified. Sold individually, it can also be sourced in case quantities of 48 units for larger projects.

Installation Notes

Installation is performed by licensed carpenters, door hardware specialists, or finish contractors. Both the door edge and the frame jamb must be mortised to the correct depth before the hinge is set, so a sharp chisel and router or dedicated mortising jig are standard tools for this work. Power down any electric door hardware or access control systems tied to the opening before beginning work. Follow local building codes and the door manufacturer's hinge spacing guidelines for proper load distribution.
