This product provides a solution for applications requiring a limited number of openings and closings. This unique thin hook can fasten directly to fabrics, carpet and loop exhibit surfaces. The thin intermeshing hook and loop are shorter for a 75% lower profile than the standard 3M(TM) Hook and Loop Fasteners.
