This patented Concealed Door Loop (CDL) is a low-cost method of transferring low voltage power from the door frame to the locking device. Whereas typical door loops are surface mounted and remain constantly visible, the CDL slides into the door and/or frame completely concealing itself when the door is closed. Designed for Continuous and Butt hinge applications that are either full mortise, half mortise, or half surface and have a standard throw. Commonly installed where ETH hinges are cost-prohibitive and surface door loops are not desired. The CDL’s aesthetic appeal will benefit retrofits and new installations alike.
