McKinney TA2714-4.5X4.5-QC4/8/12, ElectroLynx 5 Knuckle, Standard Weight Full Mortise BB Hinge

The McKinney TA2714 is an electric power-transfer hinge that carries low-voltage current from the door frame through the hinge into electrified door hardware, hidden entirely inside the hinge. It's a 4.5 by 4.5 inch, 5-knuckle, standard-weight full-mortise bearing hinge built for access-controlled commercial openings. Instead of running an exposed power-transfer loop across the gap between frame and door, the TA2714 routes the wires through concealed connectors in the hinge itself, so the power path is invisible, tamper-resistant, and clean. If you're wiring an electric lock, electric strike, or exit device with latch retraction, this is the McKinney electric hinge that feeds it.

How the McKinney TA2714 electric hinge works

An electrified door has a problem to solve: the lock or strike on the moving door needs constant power, but the power source is in the fixed frame. The TA2714 solves it through the hinge. Wires run from the frame side, through the barrel, to the door side, transferring current every time without any external loop. McKinney's ElectroLynx quick-connect system is what makes this practical. Concealed plug connectors at each end snap together, so installation is closer to plug-and-play than to splicing wires, and brass eyelets protect the conductors where they pass through. Because the wiring is coordinated to ASSA ABLOY group standards, the hinge connects cleanly to Sargent and Corbin Russwin electrified hardware.

The electric hinge installs in the center position of the door, and these hinges are typically handled because of the wiring, so confirm your hand and which QC wire count you need before ordering.

McKinney TA2714 specifications

• Bearing: TA-prefix bearing design for smooth, self-lubricating, corrosion-resistant operation.

• Application: Standard-weight, medium-frequency doors, or doors with closing devices.

• Certifications: UL listed, UL fire rated, conforms to ANSI/BHMA A156.1 and A156.7.

• Connects to: Electrified mortise and cylindrical locks, electric strikes, and exit devices requiring REX or monitoring, across ASSA ABLOY group brands.

• Finishes: Multiple including satin chrome (626/US26D).

• Warranty: 5-year warranty.

Why choose an electric hinge over a power transfer loop

For powering hardware on a swinging door, you have two real choices: an exposed power-transfer device that bridges the frame-to-door gap, or a concealed electric hinge. The hinge wins on both looks and durability. There's no visible loop to catch the eye, nothing exposed for someone to tamper with or accidentally damage, and the connection lives protected inside the hinge barrel. On corporate, healthcare, and institutional openings where appearance and reliability both matter, that's why the McKinney electrified hinge is the spec.

One practical decision drives the order: how many wires. More circuits in the opening (a lock plus a REX switch plus monitoring, for example) means more conductors, which is why the TA2714 comes in 4, 8, and 12 wire versions. Count the circuits your hardware needs and match the QC option, with a little headroom if you might add functions later.
