3M SJ-3560 Dual-Lock Fastener
3M™Dual Lock™Reclosable Fasteners consist of continuous strips of plastic backing, with plastic mushroom shaped stems protruding up from the backing strip. When two pieces of Dual Lock fasteners are pressed together, the mushroom heads interlock with one another, 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 1000 reclosures.
Dual Lock Reclosable Fasteners can replace conventional fasteners such as screws, clips, rivets, snaps and bolts in many applications. Plainbacked Dual Lock Fasteners are sewn or stapled in place. Other Dual Lock Fasteners are supplied with an adhesive backing for cost-effective installation on many substrates. Simply peel off the liner and press in place.
