Description
The HAGER HINGE BB127941226DNRP is a full mortise, standard weight ball bearing hinge designed for commercial and residential door installations. Measuring 4.5 inches x 4.5 inches, it features a non-removable pin (NRP) for added security, preventing the hinge pin from being extracted from the exposed side of the door. The satin chrome finish provides a clean, low-sheen appearance suited to both aluminum and wood door frames. Ball bearing construction reduces friction and supports smooth, consistent door swing over high-cycle use. Licensed door and hardware installers are the typical tradespeople for this product.
This hinge is suited for full mortise applications on standard-duty interior and exterior doors in commercial buildings, offices, schools, and multifamily residential projects. It fits standard door frame preparations requiring a 4.5 inch x 4.5 inch mortise cutout. The non-removable pin feature makes it particularly appropriate for outswing doors where the hinge barrel is accessible from the unsecured side. No specific compatible model families were identified in the product data.

Installation Notes
Installation is typically performed by a licensed door hardware installer or finish carpenter. Power down any electric latch or access control hardware before beginning work.
