3M SJ3551

3M SJ3551 Unlock simplicity, super strength, and ultimate ease.
The remarkable 3M™ Dual Lock Reclosable Fastener can be opened and closed up to 1,000 times before losing 50% of its original strength, for repeated access or repositioning.
The mushroom heads easily slide over each other allowing positioning of parts before they are snapped together to create a firm fastening attachment. When mated, the fasteners are hidden from view and leave you with an unbroken surface for a smooth, clean appearance.

Durable and secure, 3M™ Dual Lock™ Reclosable Fastener SJ3551 has exceptional strength through its interlocking mushroom-shaped heads (400 stem density per square inch), providing up to 5X the tensile strength of typical hook-and-loop products.
We designed this fastener with a white, acrylic, conformable foam tape protected by a removable, film liner.
This solid, pressure-sensitive foam tape features a strong, durable bond that is heat, chemical, and UV resistant.
With 3M™ Dual Lock™ Reclosable Fastener SJ3551, there is no need for any drilling, screwing, or sewing tools which makes for quick installation.
