3M™ Dual Lock™ Plain Back Reclosable Fasteners offer advanced closure alternatives to zippers, screws, snaps, hooks, bolts, and more. They offer greater design flexibility, faster product assembly, smoother and cleaner exterior surfaces and improved product performance in many applications. The fasteners consist of continuous strips of polyolefin with polyolefin stems having a mushroom-shaped top. The mushroom heads allow the fasteners to easily slide over each other allowing positioning of parts before they are snapped together creating a firm fastening attachment. Simply peel the pieces apart by hand to disengage.
