Command Access ETH4W4540626BB79 Electric Hinge 4.5x4 in

Product Description

The COMMAND ACCESS ETH4W4540626BB79 is a 4-wire electric steel base hinge designed for access control door applications. Measuring 4.5 inches by 4 inches, it provides a concealed wiring path through the hinge barrel, eliminating exposed wire loops or door-frame surface routing. The US26D satin chrome finish gives it a clean, low-glare appearance suited for commercial interior doors. Licensed security and low-voltage technicians, along with commercial door hardware installers, are the primary trades that specify and install this product. The steel base construction provides the structural durability expected in high-cycle commercial door openings.

This hinge is intended for commercial door installations where electric power transfer through the hinge point is required. Typical applications include doors fitted with electric locks, electric strikes, request-to-exit devices, or door position switches that require a continuous wire path from the frame to the door without exposed flex loops. It is suited for interior commercial doors in office, healthcare, education, and light institutional environments where a satin chrome finish is specified.

Installation Notes

Installation is performed by a licensed low-voltage technician or commercial door hardware specialist, often in coordination with an access control installer. Disconnect and lock out all power to the access control system before wiring or mounting the hinge. Follow local building codes and NEC low-voltage wiring requirements when routing conductors through the hinge. Do not exceed the rated wire gauge or voltage for the hinge conductors.
