3M™ Dual Lock™ SJ3541 is a high-strength reclosable fastener featuring interlocking mushroom-shaped stems that snap together to create a secure, hidden attachment system.
Unlike traditional hook and loop, Dual Lock provides a firm, reliable closure with an audible “snap,” ensuring proper engagement and long-term performance.
SJ3541 utilizes a rubber-based adhesive system designed for general purpose and low surface energy substrates, making it ideal for plastics, powder-coated surfaces, and other difficult-to-bond materials.
