Riddle time: What do you get when you cross a set of vise-grips with a clamp? Answer: A clamp that strips the hell out of your workpiece — well, maybe if you don’t use the optional protective pads. But no, you get a kick-ass fast-action clamp with a throat depth of 2-1/2″ that can provide 660 lbs of clamping force.
