McKinney TA2314 NRP SSF Hinge | 4.5" x 4.5" Satin Stainless Steel
The McKinney TA2314 NRP SSF is an ultra-secure standard weight bearing hinge designed for average traffic in commercial environments where high-level protection is non-negotiable. Featuring a precision .134 gauge thickness, this 5-knuckle, full mortise hinge is a premier solution for door restoration in correctional facilities, psychiatric wards, and high-security government buildings. Crafted from high-grade US32D Satin Stainless Steel, it provides maximum corrosion resistance and life-safety compliance.
Dual-Layer High-Security Features
This specialized model combines two critical security innovations to ensure the door remains locked even under extreme tampering:
- NRP (Non-Removable Pin): A hidden set screw is driven into the hinge barrel. It is completely inaccessible when the door is closed, preventing the pin from being tapped out from the exterior.
- SSF (Safety Stud): A rugged stud on one hinge leaf rotates into a matching cavity on the opposite leaf as the door shuts. This interlocks the two leaves, acting as a secondary solution for commercial door security—the door cannot be removed from the frame even if the hinge pin is successfully compromised.
Advanced Oil Impregnated Bearings (TA Prefix)
Equipped with McKinney's signature TA Prefix technology, this hinge features a one-piece, non-ferrous, self-lubricating bearing system.
- Silent & Smooth Operation: Gradually releases lubricant to ensure even longer-lasting wear and a frictionless swing.
- Environmental Protection: Engineered to resist clogging and corrosion, making it an ideal solution for door edge reinforcement in harsh or high-moisture settings.
- Maintenance-Free: Designed for longevity without the need for manual greasing, reducing facility maintenance costs.
