McKinney RCTA2714 4x4 Five-Knuckle Standard Weight Full Mortise Ball Bearing Butt Hinge with Round Corners

The McKinney RCTA2714 is a full mortise, five-knuckle standard weight ball bearing butt hinge featuring a 4-inch by 4-inch leaf size and 1/4-inch round corners. Engineered by McKinney — a trusted name in commercial and architectural door hardware — this hinge is designed for full mortise installation where both leaves are recessed into the door edge and frame. The five-knuckle construction and ball bearing pivot deliver smooth, consistent operation, making the RCTA2714 a reliable choice for demanding door opening applications.

Institutional Grade Features & Benefits

• Full Mortise Design: Both hinge leaves are fully recessed (mortised) into the door stile and door frame, providing a flush, clean profile and enhanced structural integrity at the hinge line.
• Five-Knuckle Construction: The five-knuckle barrel distributes load across more contact points than a three-knuckle hinge, improving durability and reducing wear over the life of the opening.
• Ball Bearing Pivot: Integrated ball bearings minimize friction and enable smooth, quiet swing cycles — well-suited for doors in frequent-use environments.
• Standard Weight Gauge: Steel leaf thickness of 0.130 inches (per the McKinney full-line catalog) delivers a robust, proven profile for standard commercial door applications.
• 1/4-Inch Round Corners: The rounded corner geometry (RC) ensures compatibility with mortise preparations calling for a radius corner cut, simplifying installation and maintaining a consistent aesthetic across openings.
• 4x4 Leaf Dimensions: The square 4-inch by 4-inch leaf size is a widely specified standard for commercial interior and exterior doors, providing broad compatibility with common door and frame preparations.
• McKinney Quality: Manufactured under the McKinney brand, long recognized in the architectural hardware industry for consistent dimensional accuracy and material quality in hinge products.
