3M™ Dual Lock™ Reclosable Fastener SJ3540 gives you up to five times the strength of lock and loop fasteners.
As tough polyolefin mushroom-shaped stems snap together, they provide both the tensile strength to replace traditional fasteners and a cleaner looking result.
Snap-in-place installation replaces screws and nails, snaps and rivets.
Mushroom heads lock together replacing standard hook and loop system
Ideal for indoor use to attach doors, access panels, signs and display components.
