McKinney 1458 3-1/2 x 3-1/2 Five-Knuckle Full Mortise Plain Bearing Butt Hinge — Residential Weight

The McKinney 1458 is a full mortise, five-knuckle, plain bearing butt hinge sized 3-1/2 x 3-1/2 inches, designed for light interior residential and light-commercial door applications. As a residential weight hinge, it delivers the right combination of smooth, reliable pivot action and straightforward installation for standard interior door openings. The five-knuckle barrel configuration provides a classic, finished appearance consistent with traditional residential door hardware. The hinge is field reversible, meaning it can be configured for either door hand without requiring a separate SKU — one part works across multiple opening configurations.
