Well, these DNA2 Grass Trimmer Replacement Spools are like using a freshly sharpened knife for the first time. This string absolutely slices through the grass and will make your yard look like a professional landscaping crew stops by every Saturday. The difference is in the patented DoubleHelix design. It?s stronger than other string, but it?s also made to bend and flex when it comes into contact with the hard stuff like the driveway or the porch. So it?s less likely to snap off and lasts up to 25% longer under normal use. Its oval design gives it an edge that cuts through the air with much less friction than the traditional round trimmer line. That?s right, our engineers thought about our grass trimmers right down to the shape of the string (you can imagine all the refined features in the trimmers themselves.) And its diameter is approximately 0.065?, the same gauge that professional crews use. These spools fit the Worx 20V and 32V trimmers, and even the 40V 3.0 String Trimmer/Edger model, WG180. Superior trimming and edging performance awaits when you snap these new spools of replacement line into your Worx string trimmer and edger.
