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 are designed to load into your electric Worx trimmer in seconds without hassle.


These pre-wound spools are sold individually.


Each spool contains a total of 20 feet of DNA2 DoubleHelix line.


The diameter of this line is approximately 0.08”. The line is pre-wound on spools specially designed to work on the Worx WG168, WG190 and WG191 models. Compatibility and performance on other tools isn’t likely.


These spools will not fit our 20V and 32V battery operated trimmers or the WG180. Spools compatible with those models can be found here. These spools will fit the WG168 (40V), WG190 (40V) and WG191 (56V) models.


These spools can be used in the following Worx trimmer/edger models: WG168, WG184, WG190 and WG191.


The Free Spools for Life package (WA0010) is a benefit offered to our customers who purchase select battery-operated trimmers, like the Worx Revolution. These spools (WA0014) are larger, include more lines per spool, and are specially designed to fit the WG168, WG184, WG190 and WG191 models.


Regardless of the tool or job at hand, we recommend that our customers follow standard safety precautions while using our tools, including wearing safety eyewear, gloves, appropriate shoes and clothing, and keeping hair tied back. Always refer to the owner’s manual for complete safety information before operating any tool.


If you decide the Worx spools aren’t right for you, we offer a 30-day Money Back Guarantee from the date of receipt (less shipping and handling). View more information here.
