McKinney 1414 3-1/2 x 3-1/2 Five-Knuckle Plain Bearing Butt Hinge | Full Mortise Residential Weight

The McKinney 1414 is a full mortise, five-knuckle, plain bearing butt hinge sized 3-1/2 x 3-1/2 inches, engineered for light interior residential and light-commercial doors. Designed as a residential weight hinge, the 1414 delivers reliable, smooth swinging performance in standard door applications where a full mortise installation is specified. The hinge is field reversible, making it compatible with either hand without requiring a separate part — a practical advantage for contractors, remodelers, and maintenance professionals stocking hardware for multiple openings.

Also recognized in the trade as a McKinney plain bearing residential butt hinge, this five-knuckle design provides a classic, finished appearance alongside dependable pivot performance for everyday door cycling demands.

Institutional Grade Features & Benefits

• Full Mortise Installation: Recesses cleanly into both the door edge and frame for a flush, professional finish — the standard installation method for interior residential and light-commercial doors.
• Five-Knuckle Construction: The five-knuckle barrel configuration distributes load across more bearing surfaces than a three-knuckle hinge, contributing to a refined appearance and consistent alignment over time.
• Plain Bearing Design: Suited to residential weight door applications with standard cycling frequency; no lubrication system required for routine interior use.
• Field Reversible: A single hinge works for either hand — left-hand or right-hand door swing — eliminating the need to stock separate handed units.
• 3-1/2 x 3-1/2 Inch Size: The most common residential door hinge dimension, compatible with standard interior door preparations and pre-drilled mortise locations.
• Residential Weight Rating: Matched to the door weight and frequency of use typical of interior residential and light-commercial door openings.
• McKinney Quality: McKinney is a well-established name in commercial and residential door hardware, known for consistent manufacturing tolerances and broad finish availability across its hinge lines.
