The new Quick-Grip Advantage power clamp from American Tool combines the one-handed clamping ability of the company’s Quick-Grip power clamp with the power and force of a conventional bar clamp. It delivers more than 600 pounds of clamping force. The rolled thread design of the clamp screw ensures smooth action and its serrated bar delivers extra holding power. The quick-release trigger lets you quickly and easily slide the clamp into position, then squeeze to apply pressure to your work piece. Soft, non-marring pads protect delicate work.
