McKinney TA386 NRP Concealed Bearing Hinge | 4-1/2" x 4" Heavy Weight Stainless Steel
The McKinney TA386 NRP is an industrial-strength, full-mortise architectural hinge engineered for high-security and high-traffic commercial environments. Combining a sleek 3-knuckle profile with Non-Removable Pin (NRP) technology and a heavy-duty stainless steel base, this hinge is the definitive solution for door security on out-swinging doors. It offers a sophisticated, clean aesthetic for hospitals, schools, and coastal facilities while ensuring the door cannot be removed from the frame even if the hinge barrels are exposed.
Crafted from high-grade Stainless Steel (US32D), the TA386 NRP provides maximum corrosion resistance and structural integrity. Featuring concealed vertical and lateral thrust twin anti-friction bearings, it ensures exceptionally smooth operation under heavy loads. The NRP feature includes a specialized set screw driven into the hinge barrel that is inaccessible when the door is closed, preventing unauthorized pin removal. This hinge is a vital component for any solution for door restoration, providing a professional-grade security upgrade with a heavy .180 gauge thickness.
