Ultimate Gorilla Tape® is five times stronger than our original Gorilla Tape making it our strongest tape. It is made with a weather-resistant shell, high-tensile cloth, and our double-thick adhesive. With reinforced strength, one loop holds 800+ lbs (based on tensile strength), making it great for hauling, strapping, patching, bundling, and lifting. The extra thick adhesive grips smooth, rough, and uneven surfaces. Use on wood, stone, stucco, brick, metal, vinyl, and more. Grade: Ultimate; Core Size: 3"; Dispenser Included: No; Adhesive Material: Natural Rubber.
