3M™ Dual Lock™ Reclosable Fastener SJ3550 solves attachment issues without the use of special tools or complicated, mechanical fastening systems. Our reclosable fastener uses an acrylic adhesive that bonds well to a variety of high and medium surface energy materials, including some plastics, metal, glass, and painted surfaces. This allows you to attach access doors, panels, signs, display components, and many other frequently opened and closed parts for easy, repeated access with minimal loss of bonding strength over time. It has 40 mushroom shaped stems / cm² with a 5.7 mm engaged thickness, a temperature performance ranging from -30 °C to 70 °C long-term (+95 °C short-term), and can be used indoors and outdoors.

Our innovative product is a highly practical dual lock fastener that doesn’t use special tools or complicated mechanical fastening systems. It’s five times stronger in tensile than typical hook-and-loop fasteners, and is durable enough to be opened and closed 1000 times while maintaining 50% of its original strength, making it easy to use and last longer. Foam tape backing allows for better contact with textured or irregular surfaces such as access doors, panels, signs, display components, and many other frequently opened and closed parts.
