McKinney RBTA2714 4-1/2 x 4-1/2 Five-Knuckle Standard Weight Raised Barrel Full Mortise Hinge

The McKinney RBTA2714 is a full mortise, five-knuckle standard weight steel butt hinge featuring a raised barrel design — also referred to as a raised-barrel butt hinge — that allows a door to swing clear of projecting casing trim or a deep frame return without binding. Manufactured by McKinney, a trusted name in commercial and architectural hardware, the RBTA2714 delivers reliable, low-profile pivot performance in a 4-1/2 in. x 4-1/2 in. leaf size suited to a wide range of door applications where standard-profile hinges would conflict with protruding trim profiles.

Institutional Grade Features & Benefits

• Raised Barrel Clears Projecting Trim: The elevated barrel profile is the defining feature of the RBTA2714 — it creates the necessary gap between the door edge and deep frame returns or protruding decorative casing, preventing contact and allowing smooth, unrestricted door swing.
• Full Mortise Installation: Both leaves are fully mortised into the door edge and frame, providing a flush, clean finish and maximum load-bearing contact between hardware and substrate — the preferred installation method for commercial and institutional doors.
• Five-Knuckle Construction: The five-knuckle configuration distributes door weight and operating stress across more bearing surface than three-knuckle alternatives, contributing to long-term durability and smooth pivot action under repeated use.
• Standard Weight Steel Leaf: Manufactured from steel at a leaf thickness of 0.134 in. (per the McKinney full-line catalog), the RBTA2714 provides dependable performance for standard-weight door applications.
• McKinney Quality: McKinney hinges are engineered to meet the demands of architectural and commercial construction, with consistent dimensional tolerances for straightforward field installation and reliable long-term service life.
• 4-1/2 x 4-1/2 In. Leaf Size: The square leaf dimension is a widely specified size compatible with standard commercial door and frame preparations, minimizing the need for custom mortising or template modification.
