Product Information

3MDual LockReclosable Fasteners consist of continuous strips of plastic backing, with plastic mushroom-shaped stems protruding up from the backing strip. When two pieces of the fasteners are pressed together, the mushroom heads interlock with an audible snap. To open, simply pull apart. This provides fast, secure, reclosable fastening performance for a wide range of applications. Cycle life exceeds 1,000 reclosures.

3MDual LockReclosable Fasteners are die-cut to specified size by a specialty converter and shipped to a Tier 1 supplier. The panel supplier applies 3MDual LockReclosable Fastener pieces to the headliner. The automotive manufacturer applies the mating 3MDual LockReclosable Fastener pieces to the appropriate location on the interior roof of the sport utility vehicle. The automotive manufacturer then attaches the headliner by snapping it in place.
