3M™ Dual Lock™ strips, circles and die-cuts
3M Dual Lock is a unique recloseable fastener with high performance VHB tape for mounting. It features strong, interlocking mushroom-shaped heads that slide past each other and snap with high tensile strength, but then can be reopened, making it perfect for attaching removable access panels, architectural panels, various vehicle components, portable devices like highway transponders or mobile cameras, as well as panels for signs, exhibits and displays. The audible snap gives the installer or assembly worker the confidence to know that the part has been securely attached.
Halco’s value to customers who use Dual Lock in their assembly process is our knowledge, expertise and converting capability. We have many years experience converting Dual Lock and know how to cut 3M Dual Lock tape into more usable strips, circles and die-cut shapes that fit our customer’s product design and manufacturing process. In this way, we help our customers improve their quality and productivity when using 3M Dual Lock as an attachment system.
