McKinney T4A3386 Heavy Weight Hinge | 4-1/2" x 4-1/2" Non-Ferrous
The McKinney T4A3386 is an industrial-strength, heavy-duty architectural hinge engineered for the most demanding high-traffic commercial environments. As a heavy weight, non-ferrous 5-knuckle hinge, it is specifically designed to support the physical stress of extra-heavy wood or metal doors in schools, hospitals, and government facilities. This hinge is a premier solution for door restoration, offering a robust .180 gauge thickness that far exceeds the durability of standard commercial hardware.
Key Features & Performance
- High-Frequency Performance: Designed for constant use, these hinges easily handle the rigorous opening and closing cycles of public institutions without performance degradation.
- Security NRP (Non-Removable Pin): Features an NRP set screw hidden within the barrel, preventing the pin from being removed when the door is closed—a vital solution for commercial door security.
- Corrosion-Resistant Non-Ferrous Base: Available in Stainless Steel (ANSI A5111) or Brass (ANSI A2111), providing a permanent solution for door edge reinforcement in environments prone to moisture or oxidation.
- Oil-Impregnated Bearings: The TA Prefix indicates self-lubricating, non-ferrous bearings that ensure maintenance-free, silent operation while resisting clogging and hinge failure.
- Fire Rating Note: The US32D Satin Stainless Steel finish is UL-listed and approved for use on fire-rated doors for up to 3 hours, whereas brass-based materials are not approved for fire-rated openings.
