Duct tape features a double-thick adhesive to provide a strong hold that lasts. Tough, reinforced backing and all-weather shell ensure reliable use on projects and repairs both indoors and out. Shell withstands moisture, UV rays and temperature changes. Tight weave contributes to the heft, but Gorilla Tape can still be torn by hand. Versatile design sticks to smooth, rough and uneven surfaces, including wood, stone, stucco, brick, metal and vinyl.
