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

For secure, repeatable mounting and access, the 3M SJ3550 Dual Lock reclosable fastener delivers a professional, low-profile solution for security, surveillance and cable management needs. This 3M reclosable fastener combines mushroom-head interlocking stems with a conformable foam tape backing and white acrylic VHB adhesive to bond to irregular surfaces, making it ideal for access panels, graphic attachment, small components and specialty vehicle interiors.

Engineered to withstand frequent use, the fastener can be opened and closed up to 1,000 times before losing half its original strength, and the 1" width and 50 yd roll provide long runs for large installations. With 138 mil thickness, chemical and UV resistance, and good temperature tolerance up to 120°F, it performs reliably both indoors and in sheltered outdoor monitoring environments. The hidden mating surface creates a seamless appearance while maintaining a firm hold—reducing the need for mechanical fasteners and streamlining maintenance.
