The McKinney T4A3386 is an electrified full mortise heavy weight bearing hinge built for high-traffic and high-security openings that require power transfer through the door. Measuring 4-1/2" x 4" with a five-knuckle design, it discreetly routes 12 wires from the frame to the door using ElectroLynx Quick Connect (QC12) technology, eliminating field soldering and speeding installation. Its heavy weight ball bearing construction supports demanding cycle rates while maintaining smooth, quiet operation. Finished in 626 Satin Chrome with square corners, this hinge is ideal for access control, monitoring, and electrified locking applications where reliability and a clean appearance matter.

Functional Details
The electrified hinge carries low-voltage wiring through the barrel, allowing power and signal to pass from the frame into the door for electrified locks, exit devices, and monitoring hardware. The ElectroLynx Quick Connect system uses a plug-in connector so wires can be joined without splicing or soldering, reducing installation time and error.
- Concealed electrical pathway transfers power from frame to door leaf.
- ElectroLynx Quick Connect (QC12) provides 12 wires for electrified door hardware.

Each hinge ships with the electrified leaf, factory-installed ElectroLynx Quick Connect wiring harness, and standard mounting screws for full mortise installation.
