Professional-grade reclosable fastener with interlocking mushroom heads, 170 stem density, 5X stronger than hook-and-loop, reusable 1000+ cycles, ideal for panels, signage, and trim attachment.
The 3M™ Dual Lock™ Reclosable Fastener SJ3542 is a professional-grade fastening solution designed as an easy and clear alternative to traditional fastening methods such as screws, nuts, or bolts. This innovative product features interlocking mushroom-shaped heads with 170 stem density per square inch, delivering exceptional strength with up to 5X the tensile strength of typical hook-and-loop products. The fastener is constructed with a synthetic rubber-based black PE foam tape protected by a removable film liner, utilizing a pressure-sensitive adhesive that provides quick stick and short dwell time for efficient installation.
This reclosable fastening system bonds exceptionally well to a variety of substrates including low surface energy plastics such as polyethylene and polypropylene, making it ideal for diverse industrial applications. The product delivers durable and secure fastening that can be opened and closed multiple times without compromising performance, with a closure life of 1000 cycles. Installation requires no drilling, screwing, or sewing tools, making for quick and efficient assembly. The fastener produces an audible snap when secure, verifying closure of the attachment, and can be easily disengaged by simply peeling the pieces apart by hand.
With a maximum operating temperature of 120°F (49°C) and best suited for indoor use, the 3M Dual Lock SJ3542 is recommended for access panels, interior signage, decorative trim, office partitions, and product IDs. Each case contains 4 rolls of 50 yards each, with dimensions of 0.5 inches width and 0.23 inches engaged thickness. This product maintains its strength throughout multiple attachments and detachments, providing a lightweight alternative to metal fasteners that remains hidden beneath surfaces without interfering with material integrity.
