McKinney T4A3786 NRP Heavy Weight Hinge | 5" x 4.5" 626 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. Featuring a massive .190 gauge thickness, this 5-knuckle, full mortise hinge is the premier solution for door restoration on extra-heavy wood or metal doors. Finished in 626 Satin Chrome, it offers a sleek architectural look while providing the extreme durability required for schools, hospitals, and high-frequency public 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.
- Enhanced Exterior Security: Prevents unauthorized door removal by ensuring the hinge pin cannot be tapped out from the outside.
- Optimal for Outward Swinging Doors: A vital solution for commercial door security on exterior-facing doors where the hinge barrel is exposed to the public.
- Tamper Protection: Safeguards against forced entry through hinge manipulation, offering long-term peace of mind in high-security environments.
Advanced Oil Impregnated Bearings (TA Prefix)
The TA Prefix signifies McKinney’s high-performance self-lubricating bearing system, essential for heavy-weight doors.
- Maintenance-Free Longevity: One-piece, non-ferrous bearings gradually release lubricant, ensuring even longer-lasting wear and a silent, smooth swing.
- Environmental Resilience: Engineered to resist clogging and corrosion, preventing premature hinge failure even in high-abuse or dusty environments.
- Reliable Support: Acts as a permanent solution for door edge reinforcement, maintaining perfect door alignment under the strain of constant use.
