3M™ Dual Lock™ Reclosable Fastener SJ3871, Black, Type 400, 19 mm x 45.7 m, 1 Roll/Case

The 3M™ Dual Lock™ Reclosable Fastener SJ3871 has a modified acrylic adhesive on the back of a black polypropylene reclosable fastener. This product can be used both indoors and outside in a variety of applications; and has a slim 0.24” engaged thickness and long service life.

• Durable and secure, 3M™ Dual Lock™ Reclosable Fastener SJ3871 has exceptional strength through its interlocking mushroom shaped heads (250 stem density per square inch), providing up to 5X the tensile strength of typical hook and loop products. We designed this fastener with a black, modified acrylic, very conformable foam tape protected by a removable, film liner. This solid, pressure sensitive foam tape features a strong, durable bond that is chemical and UV resistant. With 3M™ Dual Lock™ Reclosable Fastener SJ3871, there is no need for any drilling, screwing or sewing tools which makes for quick installation.
