Command Access ETH4W4545630BB91 Electric Hinge 4.5x4.5 in

Product Description

The COMMAND ACCESS ETH4W4545630BB91 is a 4-wire electric hinge designed for access control door applications. Measuring 4.5 inches x 4.5 inches, this hinge integrates concealed wiring into the hinge barrel, allowing low-voltage control signals or power to pass through the door without exposed cables or power transfer loops. The satin stainless steel finish provides corrosion resistance suited to commercial door frames and high-traffic openings. It is installed by licensed electricians or access control technicians as part of a complete electrified door hardware system.

This electric hinge is used in commercial and institutional door assemblies where power or signal transfer to electrified locksets, electric strikes, or door hardware is required. It is a direct mortise hinge replacement that eliminates the need for separate power transfer devices at the door frame. Typical installations include office entry doors, corridor doors, and secure room access points where concealed wiring is specified.
