3M™ Dual Lock™ Reclosable Fastener MP3541/42, 1 in x 4.9 yd (2.5 cm x 4.5 m)

The 3M™ Dual Lock™ Reclosable Fastener MP3541/MP3542 is the convenient alternative to traditional fastening methods, such as screws, nuts, or bolts. It is designed to deliver a durable, reclosable fastening solution (which can be opened and closed multiple times) which bonds to a variety of substrates including many plastics and low surface energy materials.

Durable and secure, the 3M™ Dual Lock™ Reclosable Fastener MP3541/MP3542 has exceptional strength through its interlocking mushroom-shaped heads, providing up to 5X the tensile strength of typical hook-and-loop products. This trial bag contains both Type 400 and Type 170 stem densities, which can both mate to Type 250. We designed this fastener with a synthetic rubber-based black PE foam tape protected by a removable, film liner. This pressure sensitive adhesive features quick stick and a short dwell time. With 3M™ Dual Lock™ Reclosable Fastener MP3541/MP3542, there is no need for any drilling, screwing, or sewing tools which makes for quick installation.
