The products feature mushroom-shaped polyolefin on a continuous polyolefin backing. When pressed together these mushroom-shaped stems interlock to provide a strong reliable attachment or high tensile closure with an audible click. 3M™ Dual Lock™ reclosable fasteners are used primarily to secure rigid and semi-rigid surfaces such as trim or door panels, instrument panel bezels, headliners, and other automotive interior trim.
Dual Lock reclosable fasteners overcome the often difficult alignment and installation problems of screws and hidden reclosable fasteners. They offer simple installation with no additional tools required. The reclosable fastener engaging area can be easily detached when repairs or maintenance are necessary and engaged together later again. Dual Lock with pressure sensitive adhesive combines the features of Dual Lock reclosable fasteners with 3M™ Acrylic Adhesive Tapes for attachment to painted sheet metal and many other automotive substrates. 3M Dual Lock reclosable fasteners are also available in various pop-in designs, die-cut shapes and slide-in constructions.
