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. No adhesive but can be attached with liquid adhesive, ultrasonically welded, stapled or sewn to fabric.

Plain backing, black with no adhesive. 170 stems per square inch. Engaged thickness of 0.160 inches.
