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.

Rated 5 out of 5 by from RUGGED This is the best lasting replacement trimmer line I have ever used. It does not break near as often as other brands, therefore I spend less time replacing the line and more time trimming. It is also the easiest to replace. I use it on my 32 V GT 2 trimmer.

Rated 5 out of 5 by from Frees Is Good As advertised these spools were free and easy to order. The only cost is for shipping. They are easy to install and even though they are small they last a long time.

Rated 5 out of 5 by from GREAT PRODUCT I bought my trimmer almost 3 years ago, instead of buying my string from a store I sent for replacement trimmer line. The reason being it is great line and trims better than anything on the market. Spoke with cs rep. and was helped without question and really fast. The delivery was quick as well. I am so happy to have this product.

Rated 5 out of 5 by from Easy to use When I bought this item I was told that the line was free for life. Well I didn't know that I would have to pay $8 plus for shipping. Seems extreme to me.

Rated 4 out of 5 by from Spool replacements I have had my lawn trimmer for several years. I have been extremely happy with ALLL my Worx products (I have several). The only thing is...yes they say they give you replacement lines free for life, but they charge you an outrageous rate for the shipping and handling. It is cheaper to go to the store and buy them. This is a very tricky gimmick.

Rated 4 out of 5 by from Forget about life time spools. Product is okay but when you want to order replacement life time line spools be prepared to shell out big bucks.
Date published: 2018-06-03
Rated 4 out of 5 by from Yep they work! Yep, the replacement spools work! Oh, hey Worx, how about starting a reclaim/recycle program where you take back the empty spools and either reuse or recycle them! Isn't that a novel idea!

Rated 3 out of 5 by from Line Quality I have been a Worx fan for years and have many of the products which I am very happy with except for the Trimmer Line. The line sticks together on the spool, almost as if the line has melted together. Waste a lot of line when this happens.
Date published: 2018-04-04
Rated 2 out of 5 by from Trimmer Line is awful Breaks very easily when trimming sidewalks and driveway. It is too thin! Worx needs to come up with a heavier line and spool head. Buying this trimmer was a big waste of money.
Date published: 2018-08-06
Rated 2 out of 5 by from Replacement Trimmer Line Interesting that this time I bought the replacement which is listed FREE for LIFE but had to pay over $17 for shipping. Then I noticed if I paid for the line for 6 it was $6.00 and shipping was free. Interesting!!!!!! I have not been as impressed with this Trimmer it does not go through the tough nut grass.

Rated 1 out of 5 by from Spools are terrible The spools are terrible. More than 50% of the spools are unusable. The line sticks together or breaks too easily. The job takes way too long when this happens. Also, when it does work properly, it is not strong enough to go through some of the thick grass.

Rated 1 out of 5 by from Replacement trim line is terrible! I love my Worx trimmer, and everything was great the first year, but in the last 2 years, all of the replacement trim line is terrible, and I’m buying the real thing, not a generic. The line consistently breaks. It almost as if it’s wound around the spool while it’s still warm. The line is stuck together on the spool in multiple places and every time you reach one of those points the line breaks. I’ve bought the replacement line in several different stores and it’s all of the same. And it started about two years ago. I never had a problem before that. Hey, Worx, if you switched trim line manufacturers you need to switch back. I just finished an hour where three different spools broke at least 15 times. The job should have taken 10-15 minutes. I would not recommend this product to anyone right now based on the quality of the replacement trim line.
