McKinney TA2771 4-1/2 Inch Five-Knuckle Standard Weight Full Surface Hinge
The McKinney TA2771 is a 4-1/2 inch five-knuckle standard weight full surface hinge designed for doors and frames where mortising is not practical or desired. As a full surface hinge, both leaves mount directly onto the face of the door and the face of the frame — no chiseling or routing required — making it an ideal solution for channel-iron frames, hollow metal frames, and similar applications where a surface-applied hinge is the correct specification. The TA2771 is a trusted McKinney hinge widely specified in commercial and institutional door hardware projects.
Institutional Grade Features & Benefits
- Full Surface Mount: Both the door leaf and the frame leaf apply directly to the surface of the door and frame faces, eliminating the need for mortising on either side — simplifying installation and reducing labor on channel-iron and comparable frame types.
- Five-Knuckle Construction: The five-knuckle barrel design provides a traditional commercial aesthetic along with smooth, consistent pivot action across the full swing of the door.
- Standard Weight: Engineered as a standard weight hinge, the TA2771 is appropriately matched to standard commercial door and hardware assemblies where a heavyweight or extra-heavyweight hinge is not required.
- 4-1/2 Inch Hinge Size: The 4-1/2 inch leaf height is a widely specified commercial hinge dimension, compatible with standard commercial door heights and common hardware schedules.
- McKinney Quality: McKinney is a long-established, specification-grade hinge manufacturer. The TA2771 is part of a line engineered for reliable, long-term performance in commercial door openings.
- Channel-Iron & Surface-Frame Applications: Specifically suited for channel-iron frames and other frame profiles where a surface-applied hinge is the correct hardware solution, the TA2771 eliminates the need for frame prep typically associated with mortise hinges.
