The Dual Lock product mates to itself, there is no male & female side. When two pieces are squeezed together their mushroom-shaped plastic stems interlock with one another (with an audible snap) to make a fastening which is stronger than Velcro. To open, simply pull apart.
Just like Velcro, the fastening can be pulled apart and put back together, over and over again. In fact, 3M's advertised life cycle is over 1000 reclosures.

250 stems per square inch and a black polyethylene foam adhesive backing. 3M Dual Lock Fastening Tape has an adhesive backing which means it can be used on a variety of surfaces. Simply peel off the liner and press in place. The adhesive back bonds to most surfaces.
Invisible - no drilling. No mechanical fastening. Strong reliable interlocking surfaces.
