Hager Hinge BB127941214 Full Mortise Ball Bearing Hinge

Product Description

The HAGER HINGE BB127941214 is a full mortise, standard weight ball bearing hinge finished in bright nickel. It is designed for commercial and residential door applications where smooth, consistent operation and a clean aesthetic are required. Measuring 4.5 inches by 4.5 inches, this hinge seats flush into mortised cutouts on both the door and frame. Ball bearing construction reduces friction across the knuckle for long service life under frequent use. Installation is performed by a qualified door hardware technician or carpenter and follows standard mortise hinge prep dimensions.

This hinge is suited for standard-weight interior and exterior door installations where a full mortise configuration is specified. The bright nickel finish makes it appropriate for finish-consistent hardware schedules in commercial offices, hotels, healthcare facilities, and residential entryways. It is sold individually and is compatible with door prep work cut to 4.5-inch mortise hinge specifications. It is not returnable once purchased, so confirm door prep dimensions and finish requirements before ordering.

Installation Notes
