Hager Hinge BB1279541226DNRP Ball Bearing Hinge 5x4.5in Nrp

Product Description

The HAGER HINGE BB1279541226DNRP is a full mortise, standard weight ball bearing hinge designed for commercial and residential door applications where security and smooth operation are required. Measuring 5 inches by 4-1/2 inches, this hinge features a non-removable pin (NRP) that prevents the pin from being driven out when the door is in the open position, a critical security requirement on outswing doors. The satin chrome finish provides a clean, professional appearance suited to high-traffic entryways. Ball bearing construction reduces friction and supports consistent, low-maintenance operation over the life of the door.

This hinge is intended for full mortise installation on standard and heavy-use interior and exterior doors in commercial and light commercial settings. It is commonly specified by door and hardware contractors, general contractors, and facility maintenance professionals. The non-removable pin configuration makes it appropriate for outswing exterior doors where hinge-side security is a code or specification requirement. Sold individually per each unit.

Installation Notes

Full mortise hinges are installed by door and hardware professionals and require precise mortise routing into both the door edge and the frame jamb to achieve a flush seating surface. Verify door and frame material, door weight, and frequency of use against the hinge weight rating before installation. Follow applicable building codes and door hardware specifications, including ANSI/BHMA standards where required. Ensure the door is properly supported during hinge installation to prevent misalignment.
