The McKinney HT4A3386 is an industrial-strength heavy weight ball bearing hinge designed for high-traffic commercial openings that demand maximum security and hygiene. Featuring a robust .180 gauge thickness, this 5-knuckle, full mortise hinge is the ultimate solution for door restoration in healthcare facilities, psychiatric wards, and correctional institutions. Crafted from high-grade US32D Satin Stainless Steel, it provides superior corrosion resistance while incorporating a specialized hospital tip for enhanced safety.
Specialized Hospital Tip & Security Features
Designed for environments where safety and tamper resistance are non-negotiable:
- Hospital Tip (HT): Features a sloped, tapered top design that prevents the hanging of objects, serving as a critical anti-ligature solution for door edge reinforcement.
- Virtually Non-Removable Pin: The hospital tip design includes a one-piece stainless steel pin that is engineered to be inaccessible, providing an essential solution for commercial door security.
- NRP (Non-Removable Pin): Equipped with an internal set screw within the hinge barrel that cannot be accessed when the door is closed, preventing unauthorized door removal.
Advanced Oil Impregnated Bearings (TA Prefix)
The TA Prefix signifies McKinney’s premium self-lubricating bearing system, engineered for "no-fail" performance:
- Maintenance-Free Operation: These one-piece, non-ferrous bearings are saturated with lubricant to ensure a silent, frictionless swing for the life of the building.
- Clog & Corrosion Resistance: Specifically designed to resist dust and sanitizing chemicals, preventing the common causes of hinge failure in medical settings.
- High-Traffic Durability: The heavy-duty ball bearing construction allows for frequent daily cycles without sagging or loss of alignment.
