Reduce downtime at the point of service with a fastening system designed for repeated opening and closing without the wear of permanent adhesives or hardware. 3M Dual Lock MP3551/MP3552 gives installers a controlled, reclosable attachment method in a 1 in x 5 yd roll, making it practical for mounting access panels, cable management components, and removable workspace accessories. Type 400 is suited for applications where a secure hold and repeat access both matter. The black profile helps maintain a clean visual finish on equipment and interior surfaces, while the roll format supports efficient cutting and placement across multiple jobs. For teams standardizing field installs or internal maintenance workflows, this fastener offers a dependable alternative to one-time mounts that complicate future service. Use it where access, alignment, and repeatability matter more than a permanent bond. It is a strong fit for IT closets, device enclosures, lab benches, and office workspace builds that need to stay serviceable over time.
