3M SJ3550 Dual Lock Reclosable Fastener with White, Acrylic, Conformable Foam Tape, 1/2" 50 yds., Type 250, Black

Secure removable mounting for panels, trim and equipment enclosures is simple with the 3M SJ3550 Dual Lock Reclosable Fastener. This 3M reclosable fastener tape combines a conformable white acrylic VHB adhesive on black PE foam with an interlocking mushroom-head closure (Type 250) to deliver consistent, reusable retention without drilling or hardware. At a practical 1/2-inch width and a full 50-yard roll, the SJ3550 minimizes material changes on the job and supports long runs for access panels, interior signage, office partitions and security or surveillance equipment mounting. The high 250 stems-per-square-inch density gives up to five times the tensile strength of typical hook-and-loop, while the foam backing accommodates surface irregularities and bonds to many plastics and low-surface-energy substrates. Designed for professional installers and integrators, this reclosable fastener reduces installation time, improves serviceability for monitoring and security systems, and keeps cable management tidy.
