3m Dual Lock Group3M™ Dual Lock™ by the yard
Dual Lock is the unique reclosable fastener made by 3M.  It is kind of like hook & loop, but with a significant increase in fastening strength.  The mushroom heads offer an audible snap, letting you know you have full engagement.  This one of a kind design allows you to rethink your design.  Dual Lock holds strong, but offers that ability to disengage as that is not readily available with nails, screws and rivets.

We offer 3M Dual Lock by the yard, with the largest selection of adhesives and stem counts around.  We also offer Dual Lock in Pre-Cut Strips and Coins.  Don't see a material or a size you need?  Have a unique application you would like some advice on?  Give us a call or an email.  We have years of knowledge and full converting capabilities and can slit, chop or die cut to your specific needs.
