Hager BB1199 NRP 4-1/2" x 4-1/2" Heavy Weight Ball Bearing Hinge
The Hager BB1199 NRP represents the pinnacle of high-security commercial door hardware. This heavy-weight full mortise hinge is specifically designed for high-frequency service on heavy doors in environments where security and durability are the top priorities. Available in non-ferrous materials like Stainless Steel and Brass, it offers exceptional resistance to the elements while maintaining its structural integrity.
Maximum Security with Non-Removable Pin (NRP)
For outward-swinging doors, the hinge pin is often the weakest point of a security system. The NRP (Non-Removable Pin) feature solves this by incorporating a hidden set screw in the hinge barrel that can only be accessed when the door is open. This prevents intruders from tapping out the pin from the outside, ensuring your door remains securely attached to the frame even under tampering. For secure exterior door installations, the Hager BB1199 NRP is an essential upgrade.
Engineered for Heavy-Duty Performance
With a robust .180 gauge thickness and four ball bearings, the BB1199 is built to support the heaviest commercial doors. The ball bearing design reduces friction, ensuring a smooth, quiet swing and preventing door sag over years of high-frequency use. This makes it the preferred choice for hospitals, schools, and high-traffic government buildings.
