Hager BB1279 NRP 4-1/2" x 4" Ball Bearing Security Hinge | US26D
The Hager BB1279 is a professional-grade full mortise ball bearing hinge designed for 1-3/4" thick doors in medium-weight or low-frequency service applications. This specific model features the Non-Removable Pin (NRP) security upgrade, making it the industry standard for outward-swinging exterior doors where security is paramount. Crafted from high-strength steel with a US26D Satin Chrome plated finish, the BB1279 combines architectural aesthetics with robust mechanical performance.
Engineered for Security and Durability
The Hager BB1279 NRP is vital for any entry where the hinge barrel is exposed to the "attack side" of the opening. The NRP (Non-Removable Pin) feature utilizes a hidden set screw in the barrel that prevents the hinge pin from being driven out by unauthorized individuals, effectively thwarting attempts to remove the door from the frame. Equipped with two ball bearings, this hinge ensures a smooth, silent swing while preventing the metal-on-metal wear common in standard plain bearing hinges.
Professional Grade Specifications
Compliant with ANSI A8112 standards, this hinge is built to rigorous industry benchmarks. It features a .134 metal gauge thickness, providing the necessary structural integrity for standard commercial wood or hollow metal doors. The US26D Satin Chrome finish offers excellent corrosion resistance and coordinates seamlessly with modern commercial locksets and exit devices.
