Hager Hinge BB127941226 Full Mortise Ball Bearing Hinge

Product Description

The HAGER HINGE BB127941226 is a full mortise, standard weight ball bearing hinge finished in bright chrome. It measures 4.5 inches by 4.5 inches and is designed for commercial and residential door applications where smooth, long-lasting swing performance is required. Ball bearing construction reduces friction at the knuckle, extending service life on frequently cycled doors. The bright chrome finish provides a clean, polished appearance suited to a range of interior hardware sets. Licensed contractors and door hardware installers are the typical end users for this type of hinge.

This hinge is used in full mortise door installations, meaning both the door edge and the door frame receive routed pockets to accept the hinge leaves flush. It is appropriate for standard weight door assemblies in interior settings. The bright chrome finish coordinates with other bright chrome locksets and closers on the same door, making it a common specification item for commercial interior suites and residential passage doors.

Installation Notes

Installation is performed by licensed door hardware installers or carpenters familiar with mortise hinge routing. Power down any electrified hardware on the door assembly before beginning work. Mortise pockets must be routed to the correct depth so hinge leaves sit flush with both door edge and frame face. Follow applicable local building codes for door hardware installation requirements.
