McKinney TA314 NRP Concealed Bearing Hinge | 4-1/2" x 4" US32D Satin Stainless Steel
The McKinney TA314 NRP is a high-security, full-mortise architectural hinge designed for modern commercial openings. Combining a sleek 3-knuckle profile with Non-Removable Pin (NRP) technology and a solid stainless steel base, this hinge is the definitive solution for door security on out-swinging doors. It offers a sophisticated, clean aesthetic for high-end offices, retail storefronts, and coastal facilities while ensuring the door cannot be removed from the frame even if the hinge barrels are exposed to the exterior.
Crafted from high-grade Stainless Steel (US32D), the TA314 NRP provides superior corrosion resistance in sterile or harsh environments. Equipped with concealed vertical and lateral thrust twin anti-friction bearings, it ensures smooth, silent operation for average-traffic doors. The NRP feature consists of a specialized set screw driven into the hinge barrel that is completely 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 without compromising the door’s clean architectural lines.
Key Features & Performance
- NRP High-Security Locking: The Non-Removable Pin is an essential solution for commercial door security, specifically engineered for exterior or outward-swinging doors where forced entry protection is a priority.
- Corrosion-Resistant US32D Finish: Solid stainless steel construction makes this an ideal solution for door restoration in laboratories, coastal areas, or sterile medical environments.
- Concealed Anti-Friction Bearings: Twin bearings are hidden within the joints to manage thrust loads, acting as a permanent solution for door edge reinforcement.
- Modern 3-Knuckle Design: Features a contemporary look with a flush pin and non-rising stainless steel pin, providing a seamless profile for high-end architectural projects.
- Narrow Width Profile: The 4-1/2" x 4" sizing is ideal for specific frame configurations where a slightly narrower leaf is required for a precision fit.
