3M MP3541/MP3542 Dual Lock Reclosable Fastener with Synthetic Rubber-Based PE Foam Tape, 1"x yds., Type 400/170, Black

Designed for fast, reliable mounting without drilling, 3M Dual Lock Reclosable Fastener MP3541/MP3542 delivers secure, reusable attachments ideal for access panels, small components and security or surveillance equipment. This mini pack supplies both Type 400 and Type 170 stem densities on a 1" wide, 14.7' (4.9 yd) roll of synthetic rubber-based PE foam tape, giving you design flexibility and strong bonding to challenging substrates including low surface energy plastics.

The interlocking mushroom-shaped heads provide high tensile strength and an audible snap so technicians can verify closure quickly on the job. With pressure-sensitive adhesive and quick-stick performance, installations are faster and cleaner than mechanical fasteners — perfect for monitoring devices, cable management and cosmetic, hidden joins on specialty vehicles or enclosures. Rated for good temperature resistance (up to 120°F/49°C), this black Dual Lock fastener balances durability with the ability to be opened and closed repeatedly.

Order the 3M Dual Lock MP3541/MP3542 mini pack to test fitment and performance for your next security, surveillance or industrial mounting application, or add it to your maintenance kit for reliable, repeatable fastening.
