The HAGER HINGE BB1279412P is a full mortise, standard weight ball bearing hinge finished in prime coat. Measuring 4.5 inches by 4.5 inches, this hinge is designed for mortise installation into door edges and frames, providing smooth, consistent swing cycles through its ball bearing mechanism. The prime coat finish makes it ready for field painting to match project specifications. It is installed by carpenters, door hardware specialists, and general contractors on commercial and residential door applications where a durable, serviceable hinge is required.
This hinge is suited for standard-duty interior and exterior door installations in residential and light commercial settings. The full mortise design requires a routed pocket in both the door edge and the door frame, delivering a flush, clean fit. The prime coat finish is commonly specified on projects where the finish coat will be applied on-site to coordinate with surrounding trim and hardware. Sold individually, it is well-suited for new construction and replacement applications alike.
Designed as an OEM-style replacement or new-install full mortise ball bearing hinge for standard residential and light commercial door applications requiring a 4.5 inches x 4.5 inches hinge preparation.
Installation is performed by qualified carpenters or door hardware technicians using a router or chisel to prepare the mortise pocket in the door edge and frame. Ensure door is properly supported and secured before removing existing hardware during replacement work. Follow local building codes and door manufacturer specifications for hinge count and placement. Prime coat finish should be lightly sanded and cleaned before applying a finish coat to ensure proper adhesion.
