McKinney TA2772 Half Surface Bearing Hinge | 4-1/2" US26D Satin Chrome

The McKinney TA2772 is a professional-grade half surface bearing hinge engineered for medium traffic and average frequency applications. This 5-knuckle steel hinge is an ideal solution for door restoration in high-use facilities such as schools, hospitals, and public buildings. Its specialized half-surface design allows the jamb leaf to be mortised into the frame while the door leaf is applied to the surface of the door, providing a robust solution for door edge reinforcement.

Advanced Oil Impregnated Bearings (TA Prefix)

The TA Prefix signifies McKinney’s high-performance oil impregnated bearing system. These one-piece, non-ferrous, and self-lubricating bearings ensure:

• Superior Longevity: Drastically reduces wear and friction for a smoother, longer-lasting door swing.
• Environmental Resistance: Engineered to resist clogging and corrosion, preventing common hinge failures in demanding environments.
  
• Maintenance-Free Operation: Provides a permanent solution for commercial door security without the need for frequent manual lubrication.

Versatile Security & Installation

• Reversible NRP (Non-Removable Pin): The pin is secured by an NRP set screw, which prevents unauthorized removal and allows the hinge to be used for both left- and right-hand door swings.
  
• Heavy-Duty Fastening: This hinge is packed with all necessary machine screws (1/2" x 12-24 FPHM) and thru bolts with grommet nuts specifically for 1-3/4" thick doors.
  
• Standard Weight Performance: Featuring a .134 thickness, it meets ANSI A8412 benchmarks for structural durability and reliability.
  
• Fire Door Compatibility: Offers an option for back plates, which are often a required solution for door surface repair and reinforcement on mineral core wood fire doors (rated above 45 minutes).
