The Channel lock WS-2 Adjustable Wrench Set contains two popular adjustable wrenches with perfectly parallel jaw surfaces that grip safely and reduce possibility of damage. Measurement scales (in. and mm) are handy for sizing nuts, pipe, and tube diameters. Its non-protruding jaw with thinner jaw profile permits easier use in more confined spaces. Its ergonomic handle is wider for a more comfortable grip. Made of Chrome Vanadium steel for durability.
