This patented Concealed Door Loop (CDL) is a low cost method of transferring low voltage power from the door frame to the locking device. 

Where as 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.

Features:

Black Anodized Finish

Easy installation and Variable mounting locations

Special 1/4" flexible conduit

Supports up to 180 degree door swing

Full 1 Year Warranty
