McKinney T4A3786 NRP Heavy Weight Hinge | 5" x 5" Satin Chrome
The McKinney T4A3786 NRP is an industrial-strength heavy weight bearing hinge engineered for the most demanding high-traffic openings in commercial construction. With a robust .190 gauge thickness, this 5-knuckle, full mortise hinge is the ultimate solution for door restoration on extra-heavy wood or metal doors. Finished in US26D Satin Chrome, it provides a sleek architectural look while utilizing specialized Oil Impregnated Bearings for maintenance-free, self-lubricating operation.
High-Security NRP (Non-Removable Pin)
The NRP (Non-Removable Pin) feature is a critical security innovation for modern facility management. It utilizes a hidden set screw driven into the hinge barrel that is completely inaccessible when the door is closed.
- Anti-Tamper Protection: Prevents unauthorized removal of the door by ensuring the pin cannot be tapped out from the exterior.
- Essential for Outward Swinging Doors: Provides a vital solution for commercial door security on exterior doors where hinge barrels are exposed.
- Forced Entry Prevention: Safeguards against intruders attempting to bypass locking hardware through hinge manipulation.
Advanced Oil Impregnated Bearings (TA Prefix)
The TA Prefix signifies McKinney’s premium self-lubricating bearing system. These one-piece, non-ferrous bearings are designed for environments where maintenance needs to be minimal.
- Superior Longevity: Drastically reduces wear and friction for a smoother, longer-lasting door swing under extreme loads.
- Environmental Resilience: Engineered to resist clogging and corrosion, preventing common hinge failures in high-abuse or dusty environments.
- Maintenance-Free Life: Acts as a permanent solution for door edge reinforcement, significantly reducing long-term lifecycle costs in busy public facilities.
