Mckinney Hinges TA271441226DQC12 Electric Hinge 4.5in

Product Description

The MCKINNEY HINGES TA271441226DQC12 is a standard weight, 5-knuckle ball bearing electric hinge designed for commercial door applications requiring wired electrification through the hinge barrel. Measuring 4.5 inches by 4.5 inches with a square corner profile, it accommodates 12 wires routed internally, supporting access control, electric locking hardware, or door monitoring systems. The satin chrome finish suits commercial interior environments where a clean, consistent hardware appearance is required. Licensed electricians or qualified door hardware technicians typically handle the wiring portion of the installation alongside door hardware installers.

This hinge is intended for commercial-grade door installations where low-voltage wiring must pass through the hinge pivot point without exposed conduit or surface-mounted wire management. Typical applications include office entry doors, corridor doors, and secure access points outfitted with electric strikes, magnetic locks, or request-to-exit devices. The square corner geometry fits standard commercial door and frame preparations. Sold individually as a single unit.
