Dual Lock fasteners consist of continuous strips of plastic backing, with plastic mushroom shape stems protruding up from the backing strip.
When two pieces of Dual- Lock fasteners are pressed together, the mushroom heads interlock with one another, with an audible snap. To open simply pull apart.
This provides fast, secure reclosable fastening performance for a wide range of applications. Used in transportation, electronics, business equipment, machinery, medical, and sign & displays markets as well as other markets.
