McKinney TA2774 Half Mortise Bearing Hinge | 4-1/2" USP Steel
The McKinney TA2774 is a high-performance half mortise bearing hinge engineered for medium traffic and average frequency commercial applications. This specialized hinge is a premier solution for door restoration in facilities like schools, hospitals, and public buildings. Its unique configuration allows the jamb leaf to be surface-applied to channel iron jambs, while the door leaf is mortised directly into the edge of the door, providing a robust solution for door edge reinforcement.
Advanced Bearing Technology
The TA Prefix signifies the use of Oil Impregnated Bearings, which are a hallmark of McKinney’s architectural excellence.
- Self-Lubricating: One-piece, non-ferrous bearings provide a continuous self-lubricating action for silent and smooth operation.
- Extreme Durability: Engineered to resist clogging and corrosion, these bearings prevent common hinge failures even in demanding environments.
- Maintenance-Free: The oil-impregnated design ensures long-lasting wear without the need for manual greasing, acting as a permanent solution for commercial door security.
Security and Versatility
- NRP (Non-Removable Pin) as Standard: The pin is secured by an NRP set screw, preventing unauthorized removal from the outside. This feature also allows the hinge to be fully reversible for left- or right-hand installations.
- Channel Iron Jamb Compatible: Specifically designed for applications where the door is hung on a channel iron jamb, offering a specialized solution for door surface repair and mounting challenges.
- Heavy-Duty Fasteners: Furnished with high-quality 1/2" x 12-24 FPHM machine screws for a secure, tamper-resistant installation.
