Advanced Safety: Hospital Tip (HT) Technology
The Hospital Tip design is a critical safety innovation specifically tailored for institutional settings. It features a one-piece non-removable pin with sloped, tapered barrel ends.
- Ligature Resistance: The tapered tips help prevent the attachment of cords or foreign objects, providing a vital solution for commercial door security in sensitive patient-care environments.
- Inherent Security: By design, the hospital tip makes the pin virtually impossible to remove, acting as a built-in tamper-resistant feature against unauthorized door detachment.
- Hygienic Design: The sloped ends reduce dust accumulation and are easier to clean, supporting strict infection control protocols in clinical facilities.
Heavy-Duty Performance & Oil Impregnated Bearings
The TA Prefix identifies McKinney’s premium self-lubricating bearing system, essential for maintaining the integrity of heavy-weight openings.
- Extreme Weight Capacity: The .190 thickness (Heavy Weight) is specifically built to support oversized, lead-lined, or high-frequency fire doors.
- Self-Lubricating Bearings: One-piece, non-ferrous bearings ensure smooth, silent operation and offer superior resistance to clogging, corrosion, and premature hinge failure.
- Maintenance-Free Longevity: Acts as a permanent solution for door edge reinforcement, significantly reducing long-term maintenance costs in busy public buildings.
