Its high resistance and flexibility make it suitable for every type of cut and for all types of trimmer heads. Efficient and fast on stony ground, it excels when cutting even robust and tough grasses. It becomes unbeatable when working on brambles and small shrubs. Its spiral shape, in addition to improving cutting performance, makes it more aerodynamic, allowing a significant reduction in noise caused by the friction of the line with air and grass, with consequent fuel savings. Ø 3.3/4 mm, 23 m long.
