3M Dual Lock Reclosable Fastener SJ3550 White 25 mm x 75 mm, 4 Strips 7100151768

Mounting items securely without drilling or permanent glue can be a challenge, especially on smooth surfaces where ordinary hook-and-loop fasteners lose grip. 3M Dual Lock Reclosable Fastener solves this with interlocking mushroom-shaped stems that snap together for a strong, vibration-resistant bond. Each pack contains four white strips, each 75 mm long and 25 mm wide, coated with a high-performance acrylic adhesive that bonds to metal, glass, most plastics, painted wood, and ceramic. The fastener withstands temperatures from -30°C to +70°C in continuous use and up to +90°C short-term, and it resists UV and water, making it suitable for indoor and outdoor applications. It can be opened and closed up to 1000 times and holds up to 15 kg per 30 cm² when fully engaged. The adhesive is permanent, so it is not designed for clean removal.

Tips

For best adhesion, clean the surface with isopropyl alcohol and let it dry before applying the strips. Press firmly for a few seconds and allow the adhesive to build strength for 24 hours before loading. To separate, peel from one edge slowly; avoid pulling straight apart to prevent damage to the surface.
