3M™ SJ3540 Dual Lock™ Reclosable Fasteners deliver a rigid mechanical closure through molded polypropylene stems that engage on contact and release with a firm pull. The black, 1-inch wide roll spans 150 feet, yielding 75 feet of usable fastening material — making it practical for high-volume or large-format mounting jobs where standard hook-and-loop falls short.
The rubber-based pressure-sensitive adhesive bonds reliably to many plastics, powder-coated metals, and low surface energy materials. This combination of substrate versatility and mechanical interlocking makes SJ3540 a go-to choice in point-of-purchase display installation, electronics assembly, industrial equipment mounting, and light manufacturing environments where repeated access to a secured component is required.
The interlocking stem design is rated for hundreds of open-and-close cycles, maintaining holding strength over extended use. Rated for continuous indoor temperatures up to 120°F. Each pack contains one roll; the black colorway suits applications where the fastener remains partially or fully visible.
