Silver Gorilla Tape is three times stronger (compared to a leading value brand duct tape) for a hold that lasts. Made with double-thick adhesive strong reinforced backing and a tough all-weather shell this duct tape is great for projects and repairs both indoors and out. The tight weave contributes to the heft but this tape can still be torn by hand. Rugged weather-resistant shell withstands moisture UV rays and temperature changes. Tape sticks to smooth rough and uneven surfaces including wood stone stucco brick metal and vinyl.
