Command Access ETH8W4545 626 CH-BB79 8-Wire Power Transfer Hinge, BB79 Style, 4-1/2"x4-1/2", Satin Chrome

For secure, professional access control installations, the Command Access Technologies ETH8W4545 Energy Transfer Hinge delivers reliable, concealed low-voltage power and signal transfer. This 8-wire power transfer hinge is engineered to route power cleanly through the hinge jamb to electric mortise and cylindrical locks, electric strikes, door-mounted card readers, exit trims and other door-mounted devices—eliminating exposed conductors and improving safety for security and surveillance systems.

The BB79-style hinge measures 4-1/2"x4-1/2" in a satin chrome finish for a commercial look that matches common door hardware. With an 8-conductor capacity and a 4' lead included, installers can support multiple circuits (power, monitoring, tamper, etc.) without additional conduit runs. The non-conductive wire access cap simplifies termination and reduces risk during commissioning. Command Access backs the hinge with a 3-year limited warranty for dependable field performance.
