Duck Brand Hold-It For Rugs is a patented non-slip latex foam coated with an adhesive backing on one side. It is designed to keep your rugs and mats in place without any floor damage. Duck Hold-It For Rugs® is repositionable and works on all types of flooring surfaces including vinyl, tile, hardwood and laminate. Do not use this product if putting a rug or mat down on top of existing carpeting. Since the foam side is going down on top of your flooring (the adhesive side bonds to the rug or mat) it will not leave an adhesive residue behind like some double-sided tapes would. Made in the U.S.If not otherwise specified widths shown in dropdown are in inches. NOTES: As with any adhesive tape product it is always the user's responsibility to determine that the product is suitable for their intended use; e.g. if you want to remove a product cleanly from a specific type of substrate please test on an inconspicuous area first.
