3M Dual Lock Fasteners 250MM

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.

• Black fastener with mushroom shaped stems, backed with an acrylic pressure sensitive adhesive
• Type 250 mates to Type 170, 250 or 400. Closes with an audible snap
• Five times the tensile strength of typical hook-and-loop fasteners
• Opens and closes 1000 times before losing 50% of its original tensile strength
• Designed to bond to metals, glass and medium to high surface energy plastics and paint
• Foam tape backing allows for better contact with textured or irregular surfaces
