3M™ Dual Lock™ Reclosable Fasteners offer advanced closure alternatives to zippers, screws, snaps, bolts and more. They can be better than conventional closure methods depending on your individual needs. These reclosable fasteners offer greater design flexibility, make for faster product assembly, result in smoother and cleaner exterior surfaces and give improved product performance in many applications.
This product is well suited for many applications where a high strength, recyclable fastening system is required. Plus, Dual Lock™ Reclosable Fasteners are appropriate for a marine environment as they retain their good performance even after exposure to ultraviolet radiation, high moisture levels and wide temperature ranges.
How do they work? When two pieces of 3M™ Dual Lock™ Reclosable Fasteners are pressed together, the "stems" flex and the "mushroom heads" slide past each other. After passing the opposing mating piece, the stems snap back into their original position and the opposing mushroom heads interlock. This interlocking action is what makes these fasteners able to provide such high-tensile strength. Yet, amazingly, they can be opened easily by simply peeling open the closure. Clear. 1" x 5 yds.
