Institutional Grade Features & Benefits
- Full Mortise Installation: Both leaves seat fully within routed mortises in the door edge and frame, producing a flush, gap-free appearance and a mechanically secure connection that resists racking and stress over high-cycle use.
- Five-Knuckle Construction: The five-knuckle barrel design provides increased bearing surface area along the pin for enhanced stability and smooth, consistent swing throughout the door's service life.
- Standard Weight Classification: Engineered for standard door weight and frequency-of-use requirements common to commercial office, institutional, and light industrial door openings.
- 1/4 Inch Round Corners: The 1/4-inch radius round corner profile on each leaf is one of the most common corner specifications in commercial hinge applications, simplifying template routing and ensuring compatibility with standard mortise jigs and door prep tooling.
- 4 x 4 Inch Leaf Size: The 4 x 4 inch (height x width open) dimension is a standard commercial hinge size suitable for a broad range of door thicknesses and weights within the standard weight category.
- Fire Rating: Approved for NFPA 80 fire-rated openings.
- McKinney Quality: McKinney is a long-established, recognized name in commercial door hardware, with a reputation for consistent manufacturing tolerances and reliable field performance.
