McKinney HT4A3786 QC12 Electrified Hospital Tip Hinge | 5" x 4-1/2" US26D Satin Chrome
The McKinney HT4A3786 QC12 is an industrial-strength heavy weight electrified hinge specifically engineered for high-security healthcare and institutional environments. Featuring the advanced ElectroLynx® Quick Connect system and a safety-focused hospital tip, this 5-knuckle, full mortise hinge is a premier solution for door restoration in facilities requiring complex electronic integration. Finished in US26D Satin Chrome, it enables a seamless, "plug and play" power transfer for ASSA brand Exit Devices on heavy, high-traffic doors.
ElectroLynx® "Plug and Play" Integration
The ElectroLynx technology simplifies the electrification of door openings by providing a standardized, reliable wiring interface:
- QC12 Configuration: Equipped with 12 wires (6 circuits) using a combination of an 8-position and a 4-position connector. This allows for complex power and monitoring requirements.
- Concealed Connectors: All wiring and plug connectors are concealed within the hinge, providing a vital solution for commercial door security by preventing wire tampering and maintaining a clean architectural look.
- UL Listed Fire Safety: Rated for use on fire-rated doors for up to 3 hours, ensuring the opening meets strict life-safety and building codes.
Specialized Hospital Tip & Security Features
Designed for safety-critical areas like psychiatric wards or high-risk institutional zones:
- Hospital Tip (HT): The tapered, sloped top design prevents the hanging of objects, serving as an anti-ligature solution for door edge reinforcement.
- Non-Removable Pin: Features a one-piece pin that is virtually impossible to remove by design, ensuring the door remains securely attached to the frame.
- Brass Eyelets: Wire portals are reinforced with brass eyelets to prevent chafing and ensure a constant, reliable flow of 4 amp continuous power.
Performance & Durability
- Oil Impregnated Bearings (TA Prefix): Utilizes self-lubricating, non-ferrous bearings that resist clogging and corrosion, ideal for high-traffic environments that require frequent cleaning.
- Heavy Weight .190 Gauge: Constructed with industrial-grade steel to support oversized doors and withstand frequent cycles without sagging or failure.
- Standardized Installation: Precision-engineered with a template screw hole pattern for exact alignment and easy field replacement in standard commercial frames.
