Hager HT-BB1279 Hospital Tip Ball Bearing Hinge – 4-1/2" x 4-1/2" US26D
The Hager HT-BB1279 is a specialized Hospital Tip (HT) Ball Bearing Hinge engineered for high-security environments, including healthcare facilities, psychiatric wards, and correctional institutions. Finished in professional US26D Satin Chrome, this 4.5" x 4.5" hinge features a sloped "hospital tip" designed to prevent the hanging of objects, providing a critical anti-ligature safety feature. Built to ANSI A8112 standards, the HT-BB1279 combines institutional strength with advanced safety components to ensure long-term performance in sensitive areas.
Anti-Ligature and High-Security Design
The Hospital Tip configuration is an essential innovation for patient and inmate safety. Hager goes beyond the tip design by integrating several security-focused mechanical upgrades as standard.
- Ligature-Resistant Tip: The sloped top knuckle prevents cords, clothing, or other objects from being looped over the hinge, mitigating self-harm risks in security areas.
- Integrated Security Components: Every hospital-tipped hinge is furnished with a Non-Removable Pin (NRP) set screw in the center knuckle, two cross pins, and a high-strength Stainless Steel hinge pin.
- Stainless Steel Bearings: To prevent corrosion and ensure a smooth swing in all environments, the ball bearing components are crafted from Stainless Steel.
- Maintenance Ready: Includes an integrated oil port for easy lubrication, ensuring the hinge operates silently and smoothly throughout its lifespan.
