Description:
The face of the wrench bar is threaded to engage threads on a nut in the adjustable jaw. The adjusting nut rides on an oval pin with a second adjusting knob, to throw the adjusting nut into or out of engagement with the teeth on the bar. This enables the wrench to operate with a quick and screw-adjust.
