Professional-grade reclosable fastener with 400 stem density mushroom heads, 5X tensile strength, synthetic rubber adhesive, ideal for interior applications with audible snap closure and 1000+ reattachments.
The 3M™ Dual Lock™ Reclosable Fastener SJ3541 is a professional-grade fastening solution designed as an innovative alternative to traditional screws, nuts, and bolts. This 2-inch wide by 50-yard roll features interlocking mushroom-shaped heads with 400 stem density per square inch, delivering up to 5X the tensile strength of typical hook-and-loop products. The fastener is engineered with a synthetic rubber-based black polyethylene foam tape protected by a removable film liner, utilizing a pressure-sensitive adhesive with quick stick and short dwell time for immediate installation without drilling, screwing, or sewing.
Designed for industrial and occupational use, this Type 400 fastener provides durable, secure attachment with an audible snap verification upon closure. The product maintains excellent performance through hundreds of reattachments, allowing pieces to be easily peeled apart by hand without compromising fastening strength. With a maximum operating temperature of 120°F (49°C) and 1000+ closure cycles, the SJ3541 is ideal for interior applications including access panels, interior signage, decorative trim, office partitions, and product identification.
The synthetic rubber-based adhesive bonds exceptionally well to various substrates including low surface energy plastics such as polyethylene and polypropylene. This reclosable fastener can mate with Type 170 and Type 250 stem densities to provide customized strength combinations based on specific project requirements. Each roll comes as a single unit per case, offering industrial users a reliable, hidden fastening system that maintains material integrity while providing superior aesthetic appearance and design flexibility.
