3M™ Dual Lock™ Reclosable Fasteners have been used extensively in transportation, electronics, business equipment, machinery, medical and sign and display markets. When the mushroom-shaped stems interlock, tensile strength is high enough to replace mechanical fasteners in many applications, yet you can readily open and close Dual Lock™ fasteners hundreds of times.

Black Type 170 Dual Lock™ with TX-1/AR7 Tape. TX-1 on liner side.
