McKinney T4A3786-5x4-1/2-US26D-CC8 Electrified Full Mortise Heavy Weight Bearing Hinge, Five Knuckle, 5" x 4-1/2", [8] Wires With Concealed Circuit, Square Corner, 626 Satin Chrome Finish

The McKinney T4A3786 is an electrified full mortise hinge built for heavy-duty commercial door applications where power must be transferred from the frame to the door. Measuring 5" x 4-1/2", this five knuckle hinge features a concealed circuit with eight wires, allowing electrified locks, monitoring devices, and access control components to operate without exposed cabling. The heavy weight bearing construction handles high-frequency and high-traffic openings with long-term reliability, and the 626 Satin Chrome (US26D) finish delivers a clean, durable appearance. Square corners make it a direct fit for standard mortised door and frame preparations.

Features

• Electrified full mortise design transfers power from frame to door through a concealed circuit.
• Eight-wire configuration supports multiple electrified hardware functions simultaneously.
• Heavy weight bearing construction is rated for high-frequency, high-traffic openings.
• Five knuckle build provides stable, smooth door movement.
• Square corner profile fits standard mortise preparations.
• Durable 626 Satin Chrome (US26D) finish resists wear over time.

Functional Details

The concealed circuit routes electrical wiring internally through the hinge, keeping the conductors hidden and protected as the door swings. This provides a continuous, tamper-resistant electrical path between the door and frame for powered locking and monitoring devices.

• Concealed Circuit (CC) provides an unexposed electrical pathway through the hinge.
• Available with wire options to support electrified door hardware and monitoring.
