3Μ Dual-Lock SJ3870 Reclosable Fastener Tape, 25mm, Black (per meter)

🔗 Heavy-Duty Fastening with Invisible Convenience

The 3M™ Dual Lock™ SJ3870 offers a high-performance alternative to screws, bolts, and rivets. Designed with a dense Type 250 interlocking stem pattern, it creates a strong, vibration-resistant closure that “snaps” together securely and can be separated and reclosed up to 1,000 times without losing holding power.

The black finish ensures a discreet, professional appearance on dark surfaces, while the modified acrylic adhesive provides excellent bonding to metals, plastics, glass, and painted surfaces – even in humid, hot, or outdoor environments.
