The mushroom-shaped heads on the 3M™ Dual Lock™ Reclosable Fastener SJ3246 easily slide over each other allowing positioning of parts before they are snapped together to create a firm fastening attachment. When mated, the black fasteners are hidden from view and leave an unbroken surface to help create a smooth, clean appearance. The pressure-sensitive, modified acrylic adhesive bonds well to low surface energy materials. and provides good adhesion for indoor and outdoor applications.

3M™ Dual Lock™ SJ3246 Reclosable Fastener is a "Type 400," which means its surface has approximately 400 stems per square inch. Stems and heads are manufactured from black polypropylene and the backing is made of 37 mils of acrylic foam tape protected by a removable liner. This construction allows for better contact with surfaces having slight texturing or surface irregularities.

To gain various levels of holding power, this fastener can be mated with different 3M Dual Lock Reclosable Fastener types. Suggested combinations of mated fasteners are:

  • Type 250 to Type 170
  • Type 250 to Type 250
  • Type 170 to Type 400
  • Type 250 to Type 400

How it works:
When two pieces of 3M Dual Lock Reclosable Fastener are pressed together, the stems flex and the mushroom heads slide past each other. After passing the mushroom heads on the opposing mating piece, a stem snaps up into its original position, interlocking with the opposing heads. The audible snap signals the fastener is engaged. The attachment formed may be as effective as screws or rivets, but will peel apart for repositioning. 3M Dual Lock reclosable fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets. Applications include attaching signs, enclosure panels, banners, repositionable shelving, vehicle ceiling panels, furniture seats and backs, marine carpeting, and orthopedic brace closures.

Today, designers, manufacturers, and consumers expect more options to secure, attach and connect surfaces. 3M Dual Lock Reclosable Fasteners offer instant installation and high-strength attachment, yet can be opened as easily as zippers. That functional flexibility, as well as superior aesthetics, reduced weight, and savings in labor and installation costs, make these innovative fasteners a popular and effective solution.
