Strength in Numbers
One little mushroom won’t accomplish much in this world, but pair him up with a few hundred of his friends and he becomes nearly unstoppable. Teamwork, that’s the idea behind the design on the 3M Dual Lock Reclosable Fastener TB3550. When joined together, these unique, mushroom-shaped stems combine to interlock with one another, generating five times the closure strength of typical hook and loop fasteners while maintaining the ability to easily peel-apart for quick access.

3M Dual Lock TB3550 Reclosable Fastener contains approximately 250 mushroom-shaped head stems per square inch. When two pieces of Dual Lock are pressed together the stems flex and the mushroom heads slide past each other. After mating, the stem snaps back into its original position, interlocking with the opposing heads with an audible snap that signals the fastener is engaged. This system can be opened and closed 1,000 times while maintaining 50% of the original tensile strength.

No Drilling, Screwing, Tightening, or Complex Installation
3M Dual Lock TB3550 uses an acrylic adhesive that bonds well to a variety of high medium surface energy materials, including some plastics, metal, glass and painted surfaces. This ensures a quick and easy installation without the use of mechanical attachment processes. The adhesive sticks quickly and reaches full strength after 72 hours. Once bonded the interlocked, mushroom-shaped stems provide an attachment that holds as well as screws or rivets, yet separates easily for access.

Versatile, Durable and Invisible
There’s no limit to the number of uses for 3M Dual Lock fasteners. The stems, mushroom tops, and film backing are constructed of clear polypropylene, and the polyolefin backing resist common solvents and alkaline solutions, making them ideal for a variety of purposes and environments. The fastener is recommended for use at temperatures ranging from -20°F/-29°C to 200°F/93”C. Hidden from view when attached, these fasteners provide a clean, unbroken surface, and stay strong through more than 1,000 open-close cycles.

Dual Lock Reclosable Fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets. They are ideal for both indoor and outdoor applications including: attaching signs, cushions, enclosure and access panels, banners, doors, adjustable shelving, vehicle ceiling panels, furniture seats and backs, and much more.

3M Scotch SJ3550 Dual Lock 250 Reclosable Fastener is a general-purpose black reclosable fastener with 250 stems per square inch, an engaged thickness of 0.23 inches and a closure life of 1,000. This black fastener has mushroom-shaped stems on a polypropylene carrier which is coated with a white, general-purpose acrylic pressure-sensitive adhesive. Type 250 stem density fasteners can mate to type 170, 250 or 400 fasteners (the higher the combined number the greater the closure strength). Mushroom-shaped stems on one side of the fastener interlock with identically shaped stems on the other side for 5X greater closure strength than hook and loop.

Dual lock type 250 fasteners are designed to bond to metals, glass, and medium-to-high surface energy plastics and paint. They can replace conventional fasteners such as screws, clips, rivets, snaps, hook and loop and bolts in many applications where access or repositioning is needed. Used to attach doors, access panels, signs, cushions, wall headliners, display components, city bus light fixtures, ceiling attachment, privacy curtain rails, sunroof trims, and wall panels. Also for POP (point of purchase), trade show exhibition and electronics, and for attaching E-ZPass tags to car windshields.

Dual lock only has one type of side; unlike products where there is a separate hook and a loop side; so rolls are typically cut in half and then mated or connected so a 10-foot roll would be used as two 5-foot strips. Made in the U.S.
