For aggressive pulling on posts and heavy-gauge sheet metal this is the heavy-duty accessory for the Magna-Spot Dent Repair Kit. Constructed from heat-treated, hardened steel, this tool features an extra large loop for attachment to your pulling devices. The self-tightening design is unique to the Magna Clamp; the harder you pull, the harder it grips. Serrated teeth grip the pins firmly without bending or breaking them while the wing-nut adjustment allows for quick release or adjustment. From Pulling to Painting, Motor Guard has a product for all of your auto body repair and refinishing needs.
