McKinney RCT2714 3-1/2 x 3-1/2 Five-Knuckle Standard Weight Full Mortise Butt Hinge with Round Corners

The McKinney RCT2714 is a full mortise, five-knuckle standard weight ball bearing butt hinge measuring 3-1/2 inches by 3-1/2 inches with 1/4-inch round corners. Manufactured by McKinney — a trusted name in architectural door hardware — this hinge is engineered for reliable, long-service performance in commercial and institutional door applications. The full mortise configuration means both leaves are recessed flush into the door edge and frame, producing a clean, professional installation with no surface-mounted hardware exposed.

Institutional Grade Features & Benefits

• Five-Knuckle Construction: The five-knuckle barrel design distributes load evenly across the full hinge length, improving durability and reducing wear at the pivot point over the life of the door.
• Ball Bearing Operation: Integrated ball bearings provide smooth, low-friction swing on heavy-use doors, minimizing maintenance and prolonging hinge life in demanding environments.
• Standard Weight Profile: The 0.123-inch steel leaf thickness (per the McKinney full-line catalog) delivers a proven balance of strength and material efficiency suited to standard commercial door and frame applications.
• Full Mortise Design: Both leaves mortise fully into the door edge and frame face, creating a flush, tamper-resistant installation consistent with commercial architectural standards.
• 1/4-Inch Round Corners: The 1/4-inch radius round corner geometry on each leaf is compatible with standard commercial door and frame preparations, ensuring straightforward drop-in replacement or new installation.
• 3-1/2 x 3-1/2 Inch Size: A widely specified hinge size for standard commercial interior and exterior door applications, offering broad compatibility with common door and frame preparations.
• McKinney Quality: Backed by McKinney's full-line manufacturing heritage, the RCT2714 is built to consistent dimensional tolerances for reliable fit and repeatable installation across large projects.
