McKinney HTA2314 4-1/2 x 4-1/2 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 featuring hospital tips, sized at 4-1/2 in. x 4-1/2 in. Engineered for demanding commercial and institutional door applications, this hinge combines the corrosion resistance of stainless steel construction with the smooth, low-friction operation of ball bearings and the safety-conscious profile of hospital-style tips — making it a trusted choice wherever a durable, full mortise hinge installation is required. The HTA2314 is manufactured by McKinney, a well-regarded name in architectural hardware known for consistent quality in commercial hinges.
Institutional Grade Features & Benefits
- Full Mortise Installation: Designed for recessed installation into both the door edge and frame, providing a flush, professional finish and maximum load-bearing support for heavy commercial doors.
- Five-Knuckle Design: The five-knuckle barrel construction offers enhanced strength and stability compared to three-knuckle alternatives, distributing door weight more evenly across the hinge barrel for long-term performance.
- Hospital Tips: Rounded, radius-style hospital tips eliminate the sharp, projecting corners of standard square-corner hinges — a critical safety feature in healthcare facilities, schools, and other occupant-sensitive environments where injury risk must be minimized.
- Stainless Steel Construction: The stainless steel base material resists corrosion, staining, and the effects of frequent cleaning and disinfectant use, making the HTA2314 well suited for high-hygiene and high-moisture environments.
- Ball Bearing Operation: Precision ball bearings at the knuckle deliver smooth, consistent swing with minimal friction, reducing wear on both the hinge and door hardware over high-cycle use.
- Standard Weight Gauge: At 0.134 in. leaf thickness, this hinge meets standard weight specifications appropriate for a broad range of commercial door applications.
- 4-1/2 x 4-1/2 In. Size: A widely used commercial hinge size compatible with standard commercial door and frame preparations, simplifying specification and replacement procurement.
Typical Applications
The McKinney HTA2314 full mortise hospital tip hinge is commonly specified for commercial, institutional, and healthcare construction projects including hospitals, medical offices, schools, government buildings, and similar facilities where a combination of durability, hygiene-friendly design, and smooth operation is required.
