Securitron's Concealed Electric Power Transfer effectively routes low voltage wires between the frame and the door's electrified hardware. The CEPT is designed to be mortised into the edges of the door and frame, generally above the second hinge. CEPT is made from 100 percent stainless steel, with no plastic parts, and is completely vandal resistant. CEPT uses common prep available through most domestic door manufacturers.
