    Product Details

    3M™ Dual Lock™ Reclosable Fastener SJ3440 is black, with 40 mushroom shaped stems / cm² and an engaged thickness of 4 mm. Our reclosable fastener is plain backed with no adhesive.

    3M™ Dual Lock™ Reclosable Fastener SJ3440 has been used extensively in transportation, electronics, business equipment, machinery, medical and sign and display markets. When the mushroom shaped stems interlock, tensile strength is high enough to replace mechanical fasteners. It's perfect for high tensile strength situations and is temperature, moisture and UV resistant. It’s an extremely versatile and secure alternative to traditional fastening methods, and works well with frequently removed parts.
