Bought this to hold a scrap piece of carpet in place in front of our woodstove. We have low-pile, indoor/outdoor carpet in our basement, and had a piece left over. We use that scrap in front of the wood-stove in case an ember falls out while loading. The scrap piece always shifted. Tried some 3M cushiony-type carpet tape that only had adhesive on one side, and that didn't stick to back of scrap, or keep it from shifting. The Intertape 9970 tape IS adhesive on both sides, and DOES keep it from shifting. Works perfectly.
