McKinney T4A3786 QC4 ElectroLynx Hinge | 5" x 4-1/2" US26D Satin Chrome

The McKinney T4A3786 QC4 is a high-performance heavy weight electrified hinge specifically engineered for high-traffic commercial doors. Featuring the innovative ElectroLynx® Quick Connect system, this 5-knuckle, full mortise hinge is the ideal solution for door restoration where electrified hardware is being integrated. Finished in US26D Satin Chrome, it provides a professional architectural appearance while enabling the seamless transfer of power from the frame to ASSA brand Electric Strikes and other electrified door components.

ElectroLynx® "Plug and Play" Integration

The ElectroLynx technology revolutionizes the electrification of door openings by removing the complexity of traditional wiring:

• QC4 Quick Connect: Features a specialized 4-wire, 2-circuit configuration with factory-installed Molex connectors. This ensures a "plug and play" installation that eliminates manual wiring errors and protects against potential shorts.
• Concealed Circuitry: All wiring is fully concealed within the hinge barrel and leaves, providing a vital solution for commercial door security by preventing tampering and maintaining the door's clean aesthetic.
• Fire-Rated Reliability: UL listed for use on fire-rated doors for up to 3 hours, ensuring your facility remains compliant with strict life-safety codes.

Heavy-Duty Engineering for High Traffic

Built for the most demanding environments, the T4A3786 QC4 is designed for longevity and smooth operation:

• Oil Impregnated Bearings (TA Prefix): Utilizes self-lubricating, non-ferrous bearings that are resistant to corrosion, clogging, and friction. This acts as a permanent solution for door edge reinforcement, even in high-abuse schools or hospitals.
• Heavy Weight .190 Gauge: The industrial-grade steel base and thick gauge construction allow this hinge to support extra-heavy wood or metal doors without sagging or alignment failure.
• Brass Eyelets: Every wire portal is protected by brass eyelets to prevent wire chafing and ensure a constant, reliable flow of power for 4 amp continuous operation.
