Command Access ETH4W4040 651 5SW RC 4-Wire Energy Transfer Hinge, 4" x 4", Bright Chrome

For secure, professional access control installations, the Command Access Technologies Energy Transfer Hinge (ETH) puts low-voltage power where you need it without exposed wiring. This 4-wire energy transfer hinge routes power cleanly through the hinge jamb to electric mortise and cylindrical locks, electric strikes, door-mounted card readers and other door-mounted security devices — enabling simplified monitoring and surveillance system integration. The ETH4W4040 features a standard 4" x 4" size and a bright chrome finish that matches commercial hardware, plus a complimentary 4' lead to reduce on-site wiring time. A non-conductive wire access cap protects conductors and helps prevent shorts, improving reliability for 24/7 security and networked access control systems. Designed for installers and facility managers who need a neat, code-friendly solution, this hinge minimizes retrofit complexity while supporting electric lock, latch pullback and exit trim applications.
