Description:
The swinging hook jaw with a spur pivots on a sliding yoke. A set screw in one side of the yoke slides in a slot in the wrench shank, and can be removed to allow the yoke and hook jaw to be removed. The wrench shank has wedge-shaped notches to engage the spur on the hook jaw. In use, tipping the hook jaw back disengages the spur to allow size adjustment.
