ABSTRACT:
A lightweight, adjustable wrench comprising of a moveable jaw with a reach that is shortened or lengthened with a strap or a cable. The loose end of the strap or cable is secured to the wrench's shank by a cam lock, or similar locking device. Since the strap or cable is the means for the wrench's jaws adjustment, a quicker and easier fit to the pipe or object to be gripped can be obtained. The wrench is more convenient to adjust, since the means for adjustment are located near the handle of the wrench as opposed to the shank end of present designs. The strap or cable adjustment also allows the wrench's shank and handle to be designed hollow and a larger diameter to reduce weight. The wrench can be made in any proportion for any sized application.
