Hager BB1168 4.5" x 4.5" Heavy Weight 5-Knuckle Ball Bearing Hinge
The Hager BB1168 is a high-performance, heavy-weight door hinge engineered for demanding environments. Designed for use on heavy doors or those requiring high-frequency service, this hinge is a staple in commercial construction. With a robust .180 gauge steel construction and a 5-knuckle design, it provides the structural integrity needed for high-traffic entrances.
Engineered for Performance and Security
This model features four ball bearings, ensuring exceptionally smooth operation even under the stress of heavy door loads. The full mortise configuration allows for a seamless, flush installation. Additionally, the Non-Removable Pin (NRP) feature (available on this model) provides a critical layer of security for exterior-swinging doors by preventing the pin from being removed from the outside.
Certified Safety and Standards
When safety is non-negotiable, the Hager BB1168 delivers. It is UL Fire Rated for use on door assemblies for up to three hours, fully complying with NFPA80 requirements. Furthermore, it meets ANSI/BHMA A156.1 and ANSI A8112 standards, confirming it has passed rigorous testing for durability, finish, and functional reliability.
