McKinney T4A3386 NRP Heavy Weight Hinge | 4-1/2" x 4" Stainless Steel
The McKinney T4A3386 NRP is an industrial-grade heavy weight ball bearing hinge designed for high-traffic commercial openings where security and corrosion resistance are paramount. Featuring a robust .180 gauge thickness, this 5-knuckle, full mortise hinge is a premier solution for door restoration on oversized or extra-heavy doors. Crafted from high-grade US32D Satin Stainless Steel, it provides a sleek architectural finish while offering the structural integrity required for demanding environments like hospitals, schools, and coastal facilities.
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 to the public side.
- 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 heavy 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.
