The Craftsman 4-inch strap wrench is a must-have tool that no home owner, do-it-yourselfer, or professional should be without. This handy strap wrench is ideal for taking off an oil filter, installing a hard-to-reach drain pipe, or just opening and closing bottles and jars. The applications are endless. The small-handled wrench manages items up to 4 inches in diameter. Made of cushioned plastic, the handles are comfortable to hold. The straps are made of strong, reinforced rubber that grips most anything and will not break. Just slip the strap around the item, tighten it until it grips securely, and turn. Friction keeps it from slipping. Backed by Craftsman's Hand Tool Full Warranty.
