McKinney TA786 NRP Concealed Bearing Hinge | 4-1/2" x 4-1/2" Heavy Weight 3-Knuckle
The McKinney TA786 NRP is a high-security, heavy-duty architectural hinge designed for out-swinging doors in high-traffic commercial environments. This model combines a sleek 3-knuckle design with Non-Removable Pin (NRP) technology, making it the definitive solution for door security. It provides a clean, modern aesthetic for schools, hospitals, and government facilities while ensuring the door remains impenetrable from the exterior, even if the hinge barrels are exposed.
Equipped with concealed vertical and lateral thrust twin anti-friction bearings, the TA786 NRP delivers smooth, silent operation under extreme weight. The NRP feature utilizes a hidden set screw driven into the hinge barrel, which is inaccessible when the door is closed, preventing intruders from removing the pin to gain entry. This hinge is a vital component for any solution for door restoration, offering a professional-grade upgrade for high-security perimeters.
