Command Access ETH4W4040 640 5SW 4-Wire Energy Transfer Hinge, 4" x 4", 5 Knuckle Standard Weight, 26AWG, Oxidized Satin Bronze Over Copper Plated Oil Rubbed Finish

Pass low-voltage power cleanly through the hinge jamb to the lockset with the Command Access Technologies ETH4W4040 energy transfer hinge. This purpose-built door hinge supplies concealed power to electric mortise and cylindrical locks, electric strikes, exit trims, latch pullback devices and door-mounted card readers—removing bulky conduit runs and exposed cabling that can compromise security installations.

Built as a 4x4, 5-knuckle standard-weight hinge with 26AWG conductors and a factory 4-foot lead, the ETH4W4040 delivers reliable low-voltage connectivity while maintaining a finished, professional appearance. The oxidized satin bronze over copper-plated oil-rubbed finish provides corrosion resistance and aesthetic continuity for commercial and institutional openings. A non-conductive wire access cap and clean internal routing reduce tampering risk and simplify commissioning for access control, surveillance and monitoring systems.

For security integrators and facility managers seeking a low-profile, robust solution for powering door hardware, the Command Access ETH4W4040 minimizes installation time and enhances system reliability. Ideal for access control projects and retrofit applications—specify or order today to streamline your next security door installation.
