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. High Temperature and solvent resistant. Non-woven backing can be very helpful if attachment with liquid adhesive is desired.

Plain backing, black with reinforced nonwoven fabric backing. 400 stems per square inch
