3M™ Dual Lock™ Reclosable Fastening System SJ3550CF, Black, 25 mm x 5 m (4 Rolls per Case)

The 3M™ Dual Lock™ Reclosable Fastening System SJ3550CF is an easy alternative to traditional fastening methods such as screws, nuts, or bolts. It is designed to provide a durable, reclosable fastening solution that adheres to a variety of substrates, including metals, glass, and plastics such as acrylics, polycarbonate, and ABS. This fastening system gives the adhesive a black appearance.

Easy Opening: The durable and secure 3M™ Dual Lock™ Reclosable Fastening System SJ3550CF provides exceptional strength thanks to its interlocking mushroom-shaped heads (stem density of 40 per cm²), offering up to 5 times the tensile strength of typical hook fasteners. We designed this fastening system with a clear acrylic tape protected by a removable film liner. This solid, pressure-sensitive tape creates a strong, long-lasting bond, resistant to heat, chemicals, and UV light. With the 3M™ Dual Lock™ Reclosable Fastening System SJ3550CF, there is no need for drilling, screwing, or sewing, which speeds up installation.

Design Flexibility: The 3M™ Dual Lock™ Reclosable Fastening System SJ3550CF features mushroom-shaped heads that slide easily over one another, allowing parts to be positioned before being snapped together. This fastening process creates a durable bond and enables quick assembly with high design flexibility. Our reclosable fastening systems can also be combined with different stem densities for various closure strength levels and system performance. 3M™ Dual Lock™ systems emit an audible click when securely fastened, providing closure verification. To release, simply pull the pieces apart by hand. These systems retain their strength after multiple openings and closings. This product, a lightweight alternative to metal fasteners, remains hidden beneath surfaces and does not compromise material integrity, offering aesthetic improvements and design flexibility.

Hundreds of Openings and Closings on Demand: When two pieces of 3M™ Dual Lock™ Fastening Systems are engaged, the stems flex, and the mushroom heads pass over each other. Once engaged, the stems return to their original position, and the mushroom heads interlock. These fasteners can provide high tensile strength but can be easily separated by peeling or pulling apart. This product is suitable for many indoor and outdoor applications where a reclosable, versatile, and high-strength fastening system is required.

Long-Lasting Performance: Not all design needs are easy to meet, but fastening can be simplified. When a strong, reliable, yet removable closure is required, 3M™ Dual Lock™ Reclosable Fastening Systems are the simple alternative to traditional fastening methods such as screws, nuts, and bolts.
