ABSTRACT:
A cable lock for doors in which a loop at one end of a cable is attached by a bolt or screw to a building wall adjacent to a door and a larger loop at the opposite end of the cable is applied over and around a doorknob to limit the extent to which the door may be opened. In one embodiment of the lock, a metal sleeve encircles the major portion of the cable between the end loops. The metal sleeve increases the resistance of the device to cutting by bolt cutters, saws, and other burglary tools. A sleeve of resilient material encircles at least part of the cable between the end loops and serves to protect the door and door frame from damage upon contact of the cable therewith.
