3M Dual Lock Sitemap

3M SJ4575 Dual Lock Low Profile Reclosable Fasteners can replace conventional fasteners such as screws, clips, rivets, snaps, hook and loop and bolts in many applications where access or repositioning is needed. Amazingly thin and reclosable, yet strong, 3M Dual Lock Low Profile fasteners are thinner and more flexible than other reclosable fasteners. 3M SJ4575 is backed with 3M 300 LSE Laminating adhesive, giving it an excellent bond to many substrates including polypropylene, polyethylene, metal, finished wood and many others. Used in POP (point of purchase), trade show exhibition and electronics, Dual Lock low profile reclosable fasteners attach ceiling tiles, carpet, seat cushions, trade show graphics, access panels, wall panels, and small electronic devices. They are also great for attaching E-ZPass tags to car windshields. 3M typically recommends 4 square inches of fastener per pound of static load for their low profile dual lock products. Dual lock only has one type of side; unlike velcro where there are 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. Low profile dual lock has about 700 stems per square inch, but the stems are much shorter than standard dual lock which has either 170, 250 or 400 stems per square inch. They let you make a much thinner joint (an object being mounted would not stick out as far), but it doesn't have the holding power of standard dual lock. However, for smaller, lightweight items it is ideal.

3M SJ3551 Dual Lock 400 Reclosable Fastener is a general-purpose black reclosable fastener with 400 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 400 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 400 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 velcro where there are 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.

They are also great for attaching E-ZPass tags to car windshields. 3M typically recommends 4 square inches of fastener per pound of static load for their low profile dual lock products. The 10-foot sizes are cut from longer source rolls (only the 5/8 inch x 10-foot size of SJ4570 which is specifically labeled as *retail-packaged comes in a package suitable for resale). Dual lock only has one type of side; unlike velcro where there are 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.
