McKinney T4A3386 NRP Heavy Weight Hinge | 4-1/2" x 4" US32D Stainless Steel
The McKinney T4A3386 NRP is an industrial-strength heavy weight bearing hinge engineered for the most demanding high-traffic commercial environments. Featuring a robust .180 gauge thickness, this 5-knuckle, full mortise hinge is a premier solution for door restoration on extra-heavy wood or metal doors. Crafted from high-grade US32D Satin Stainless Steel, it provides superior corrosion resistance, making it an ideal choice for hospitals, schools, and coastal facilities.
Maximum Security with NRP (Non-Removable Pin)
The NRP (Non-Removable Pin) feature is a critical security upgrade for exterior or high-risk openings. It utilizes a hidden set screw within the hinge barrel that is completely inaccessible when the door is closed. This provides:
- 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 doors where the hinge barrel is exposed to the public side.
- Tamper Protection: Safeguards against forced entry via hinge manipulation, offering peace of mind for high-security areas.
Specialized Oil Impregnated Bearings (TA Prefix)
The TA Series features one-piece, non-ferrous, and self-lubricating bearings that ensure even longer-lasting wear. These bearings provide:
- Maintenance-Free Operation: The oil-impregnated design gradually releases lubricant, reducing friction and the need for manual oiling.
- Environmental Resilience: Engineered to resist clogging and corrosion, preventing hinge failure in harsh or high-frequency use conditions.
- Smooth Performance: Acts as a permanent solution for door edge reinforcement, maintaining a silent and effortless swing over millions of cycles.
