Frequently Asked Questions

  • What makes Worx DNA2 DoubleHelix line special?

    DNA2 DoubleHelix cutting line has a unique aerodynamic shape for reduced drag and superior trimming and edging performance to ensure a healthier cut for your lawn. With over 100lbs of tensile strength, Worx DNA2 DoubleHelix cutting line offers more durability and flexibility for a longer life. These pre-wound spools can be loaded into your 20V or 32V Worx trimmer in seconds without hassle.

  • How many spools are in each package?

    Each package contains 2 pre-wound spools.

  • How much line is on each spool?

    Each spool contains 10 feet of DNA2 DoubleHelix line.

  • What’s the diameter of this line? Can it be used in trimmers other than Worx trimmers?

    The diameter of this line is approximately 0.065”. The line is pre-wound on spools specially designed to work on Worx 20V and 32V battery operated trimmers. Compatibility and performance on other tools isn’t likely.

  • Do these spools fit the 40V Worx trimmer/edger? Do they fit the 56V trimmer?

    We have two different model 40V trimmers. These spools will fit the Worx 40V 3.0 String Trimmer/edger model WG180, which has a similar shape and size to our 20 and 32V trimmers, but they will NOT fit our model WG190 40V trimmer or the 56V model WG191. For spools to fit the 40V model WG190 or 56V model WG191, click here.

  • What trimmer models are compatible with these spools?

    These spools can be used in the following Worx trimmer/edger models: WG150, WG151, WG151.5, WG152, WG153, WG154, WG155, WG155.5, WG156, WG157, WG160, WG160.1, WG160.2, WG160.3, WG160.4, WG162, WG163, WG165, WG166, WG166.1, WG167, WG174, WG175, WG175.1, WG176, WG180.

  • Will these spools fit the WG124 trimmer?

    These spools are too small to fit the WG124 trimmer. You can find spools to fit the WG124 here.

  • What’s the difference between this and the Free Spools for Life package (WA0010)?

    This model (WA0004) is a two-pack of spools. Our Free Spools for Life package (WA0010) is a benefit for customers who have taken advantage of a special TV or internet offer from Worx. The spools inside the packages are the same, it is the quantity that is different. To visit the Free Spools for Life page, click here.

What happened to the free spools of line.  I had my first trimmer since the late ‘90’s I believe. I now have the newer one and the line is going to cost me $3.50 a spool?  May have to think about a different trimmer.
