Command Access ETH4W4545625BB79 Electric 4-wire Hinge

Product Description

The COMMAND ACCESS ETH4W4545625BB79 is a 4-wire electric hinge designed for access-controlled door applications. Built on a steel base and finished in US26 Bright Chrome, this hinge transfers low-voltage wiring through the door frame to power electric locks, electromagnetic holders, or other door-mounted electrified hardware. At 4.5 inches x 4.5 inches, it fits standard full-mortise hinge preps on commercial-grade hollow metal and wood doors. Installation is performed by licensed locksmiths, access control technicians, or commercial door hardware specialists working within electrified openings.

This hinge is suited for commercial interior and exterior door openings where concealed wiring transfer is required between the frame side and the door-mounted device. It eliminates the need for exposed conduit or surface-mounted wire runs at the door edge, making it appropriate for retrofit and new-construction access control projects. The 4-wire configuration supports common access control functions including power, ground, and signal leads for electric latch retraction or monitoring circuits.
