3M™ Dual Lock™ Reclosable Fastener SJ3561 is up to five times stronger in tensile strength than typical hook-and-loop fasteners. As tough, polypropylene mushroom-shaped stems snap together, they provide both tensile strength to replace traditional fasteners and a cleaner looking result. These fasteners can be opened and closed up to 1000 times, before losing 50% of the original tensile strength.
Snap-in-place installation replaces screws and nails, snaps, and rivets

Solve Attachment Challenges in an Instant
The mushroom-shaped heads on the 3M™ Dual Lock™ Reclosable Fastener SJ3561 easily slide over each other, allowing for positioning of parts, before they are snapped together to create a firm fastening attachment. When mated, the fasteners are hidden from view and leave an unbroken surface to help create a smooth, clean appearance.

Select the right Fastener for the Job
3M™ Dual Lock™ Reclosable Fastener SJ3561 is a "Type 400," which means its surface has approximately 400 stems per square inch. To gain various levels of holding power, this fastener should 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 rapid 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.
