McKinney TCA2714 4-1/2 x 4-1/2 Five-Knuckle Standard Weight Concealed Bearing Full Mortise Butt Hinge
The McKinney TCA2714 is a full mortise, five-knuckle standard weight steel butt hinge featuring concealed antifriction bearings housed entirely within the knuckle barrel. This design delivers the smooth, low-friction operation of a bearing hinge while maintaining a clean, traditional barrel appearance — the bearings remain hidden from view, making the TCA2714 visually indistinguishable from a plain-bearing hinge yet functionally superior for high-cycle door applications. Also referenced as the McKinney TCA2714 4-1/2x4-1/2 concealed bearing hinge, this is a genuine McKinney product built to the exacting tolerances of the McKinney full-line catalog.
Institutional Grade Features & Benefits
- Concealed Antifriction Bearings: Bearings are recessed inside the knuckle, eliminating exposed bearing surfaces for a streamlined barrel profile while still reducing pivot friction and wear during repeated door cycles.
- Five-Knuckle Construction: The five-knuckle barrel distributes load across more contact points than a three-knuckle hinge, providing enhanced strength and stability for standard-weight door applications.
- Full Mortise Installation: Both leaves are fully mortised into the door edge and frame, producing a flush, professional installation that keeps the hinge leaves flush with the door and jamb surfaces.
- Standard Weight Steel Leaf: Steel leaves at a precise 0.134 in. gauge (per the McKinney full-line catalog) deliver the correct thickness for standard-weight door and frame applications, ensuring proper fit in mortise pockets cut to specification.
- Clean Barrel Aesthetics: The hidden bearing design preserves the classic butt hinge silhouette — well-suited for architectural environments where a traditional appearance is required.
- McKinney Heritage: McKinney is a long-established, respected name in commercial door hardware, and the TCA2714 reflects that legacy of precision manufacturing and consistent quality.
