Command Access ETH4W4545 639 5SW 4-Wire Energy Transfer Hinge Square Corner, 4-1/2 X 4-1/2", Satin Bronze

Keep low-voltage power safely concealed while maintaining seamless door operation. The Command Access Technologies Energy Transfer Hinge (ETH4W4545) is a purpose-built door hinge that transfers 4-wire low-voltage power from the jamb to the lockset without exposed conductors—ideal for electrified mortise and cylindrical locks, electric strikes, and door-mounted card readers. The satin bronze, 4-1/2" x 4-1/2" square-corner design delivers a professional finish that complements commercial interiors while meeting the demands of security and surveillance installations.

Technicians benefit from a pre-attached 4' lead and a non-conductive wire access cap that speeds up installation and ensures safe, code-compliant wiring. The hinge reduces wiring stress on moving parts and minimizes troubleshooting in access control and monitoring systems. Rugged construction and a 3-year limited warranty give facility managers confidence in long-term reliability.

Use the ETH4W4545 when upgrading to electrified hardware or when running power to exit devices and door-mounted readers. Order now to streamline your access control installs and maintain a clean, secure door solution.
