3M SJ4570 Dual Lock™ Reclosable Fastener, 1" x 50 yd x 0.098", Clear, 2/Case, MFR ID 7000002105

3M™ Dual Lock™ Reclosable Fastener SJ4570 Low Profile is a low surface energy adhesive on the back of a clear polypropylene reclosable fastener. This product is half the thickness of standard 3M™ Dual Lock™ Reclosable Fasteners, providing a low profile attachment. An alternative to screws and bolts, this hidden fastener provides a snug fit and smooth aesthetic appearance. - When two pieces of 3M dual lock low profile reclosable fasteners are pressed together, the "mushroom heads" interlock with one another creating an audible snap, indicating the fastener is engaged. The dual lock low profile reclosable fastener is thinner allowing it to be more flexible than similar reclosable fasteners. Dual lock low profile reclosable fasteners consist of continuous strips of plastic backing, with tiny plastic mushroom shaped stems protruding up from the backing strip.
