The Original Einhell replacement thread Super Cut Line 2.0 is a spare part for thread spools used with grass trimmers and scythes. Due to its angular or square shape, the trimmer thread has four sharp edges. These sharp cutting edges cleanly slice through the blades of grass and thus produce an optimum cut. This is efficient trimming and mowing at its best! The entire trimmer thread is 15 metres long, made of rugged and durable nylon and has a diameter resp. thickness of 2.0 mm.
