3M™ Dual Lock™ Reclosable Fastener TB3551/TB3552 gives you up to five times the strength of hook-and-loop fasteners - without special tools. As tough, polyethylene mushroom-shaped stems snap together, they provide both tensile strength and a clean looking result. Our remarkable fasteners can be opened and closed over and over, up to 1000 times for repeated access or repositioning.
