Hager BB1191 NRP 4-1/2" x 4-1/2" Ball Bearing Hinge – Non-Ferrous Security
The Hager BB1191 NRP is the ultimate solution for exterior doors in corrosive environments, such as coastal regions or high-moisture commercial facilities. As a non-ferrous hinge, it is crafted from Brass or 304L Stainless Steel to prevent rust and oxidation. Designed for medium-weight doors requiring low-frequency service, this hinge combines architectural elegance with industrial-grade durability.
Advanced Security with Non-Removable Pin (NRP)
Security is paramount for outward-swinging doors where the hinge barrel is exposed. The NRP (Non-Removable Pin) feature includes a hidden set screw that secures the pin in place, making it impossible to tap out from the outside. This vital innovation protects your facility from unauthorized entry via hinge manipulation, providing essential enhanced security and peace of mind for any secure door installation.
Material Excellence and Fire Safety
The Hager BB1191 series offers two primary material bases to suit your project requirements. The Stainless Steel models (Type 304L) meet ANSI A5112 standards and are suitable for most environments. The Brass models meet ANSI A2112 and offer a classic look with various plated finishes.
Important Note: While Stainless Steel hinges are fire-rated, hinges with a Brass base material are not permitted for use on UL Fire Rated Door Openings per NFPA 80 regulations.
