Solve Attachment Challenges in an Instant
The mushroom-shaped heads on the 3M™ Dual Lock™ Reclosable Fastener TB3561/TB3562 easily slide over each other allowing for the positioning of parts before they are snapped together. When mated, the fasteners are hidden from view and leave an unbroken surface to help create a smooth, clean appearance. This Trial Bag includes a 10 ft mated strip of 400/170 stem density, a combination proven successful for a majority of indoor and outdoor applications. The clear acrylic adhesive is designed to bond to metals, glass and high surface energy (HSE) plastics.

How the Dual Lock Reclosable Fastener 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 and marine carpeting.
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.
