Now you can crimp any crimp bead of "medium" size (2-3mm) and various shapes - quick and easy! The Dual Euro Crimper has two forming cavities for round, tube and combination crimps of slightly varying sizes. But wait...the new, true ergonomic handles give you a great grip, too, because they are made from sanoprene - a special compound - with excellent surface tack. Dual Euro Crimper jaws are precision made for years of service and beautiful results every time.
