McKinney HTA2314 4-1/2 x 4 Five-Knuckle Standard Weight Hospital Tip Hinge — Full Mortise Stainless Steel Ball Bearing Butt Hinge
The McKinney HTA2314 is a full mortise, five-knuckle, standard weight stainless steel ball bearing butt hinge with hospital tips, sized 4-1/2 inches by 4 inches. Designed for demanding commercial and institutional door applications, this hinge combines the cleanability and corrosion resistance of stainless steel construction with the smooth, low-friction performance of ball bearings and the distinctive hospital tip profile — also commonly referred to as a hospital-style tip or sanitary tip — which eliminates exposed fastener points and sharp corners to support hygienic environments and reduce injury risk. As a full mortise hinge, both leaves recess flush into the door edge and frame, providing a clean, professional installation consistent with commercial door hardware standards. Part number HTA2314 is a genuine McKinney hinge, a brand recognized across the architectural hardware industry for precision-manufactured butt hinges used in commercial, institutional, healthcare, and high-traffic settings.
Institutional Grade Features & Benefits
- Hospital Tip Profile: The hospital-style (sanitary) tip design eliminates protruding fastener points and sharp corners at the top and bottom of the hinge barrel, supporting hygienic maintenance and reducing snag and injury hazards — a standard specification in healthcare, educational, and institutional facilities.
- Five-Knuckle Construction: The five-knuckle barrel configuration provides superior strength distribution along the hinge pin, contributing to long-term stability and reduced play in the door over time compared to three-knuckle designs.
- Ball Bearing Operation: Precision ball bearings within the knuckles deliver smooth, low-effort door swing and reduce friction-related wear, making this hinge well-suited for high-cycle, heavy-use openings.
- Full Mortise Design: Both leaves mortise flush into the door edge and frame face, producing a clean finished appearance and secure mechanical connection — the preferred installation method for commercial and institutional wood and hollow metal doors.
- Stainless Steel Material: Stainless steel construction delivers excellent corrosion resistance and a cleanable surface, supporting installations in moisture-prone, frequently sanitized, or high-humidity environments.
- Standard Weight Classification: Sized and specified for standard weight commercial door applications, providing the appropriate mass and leaf thickness for the intended door weight and frequency-of-use category.
- Precise Leaf Thickness: Steel leaf gauge of 0.134 in. delivers consistent performance within the standard weight class, as published in the McKinney full-line catalog.
- 4-1/2 x 4 Inch Size: A widely specified hinge size for standard commercial door heights and weights, compatible with common commercial door and frame preparations.
