3M Dual Lock Tape

Using the same principles as velcro, 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. Black, 1” wide, polyproplyene reclosable fastener with a pressure sensitive, self-adhesive backing. Available with 170 (SJ3552) or 400 (SJ3551) stems per square inch.


Use SJ3551 with itself to obtain a strong, easy fixing. Use SJ3551 with SJ3552 for a weaker fixing which is easier to re-apply.
