About this item
Highlights
- [2-PACK] Each spool is 10 feet of the patented DoubleHelix DNALINE2, which is an oval-shaped aerodynamic design that makes for cleaner cuts
- [FLEXIBLE] This string stretches just a little when it hits hard surfaces like concrete or the deck which lessens the impact and makes it last longer
- [LESS DRAG] That aerodynamic design cuts through the air as well as the grass, putting less strain on the string trimmer’s motor, extending the life of the tool
- [100 LBS OF TENSILE STRENGTH] This string is strong, too. Older trimmer line was typically only made to handle 68 lbs, and would snap and fray quicker
- [DO IT YOURSELF. DO IT BETTER. DO IT WITH WORX.] WORX tools are engineered with cutting-edge technology, and above modern efficiency standards, so you can build a cost-effective tool collection that’s been designed to last
Description
Every homeowner wants the same thing: A clean and sharp looking lawn with less work. 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 0.065in, 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. Superior trimming and edging performance awaits when you snap these new spools of replacement line into your Worx string trimmer and edger.

Bait and Switch
I like Worx products. I thought I had free spool replacements. I was able to get 6 replacements twice but when I tried to order them last week I was not given that option.

Good product.
I purchased the weed eater at least 15 yrs ago i think. It still runs like a champ! I had signed up for the free replacements way back when,received them,cant find them now! So ordered 2 more and they came right away. Thanks for making a good product and the quick turn around on my purchase!

String breaks constantly
The string is terrible, it breaks constantly. I just have to stop every 30 seconds to reload it. It is almost as if it melts together. I am so disappointed as this is a brand new trimmer and I was so excited to get it.

Excellent for even senior citizens
Workx is the best because it’s so easy to use, lightweight and I’ve had my trimmer for years, the spools are a no brainer for ease of changing and operation. Thank you Workx for making such a good product for seniors to use!!!!!

Effective string trimmer
Effective string for the cordless trimmer and works well. When I purchased the trimmer it was supposed to be with a lifetime supply of replacement filled string trimmer spools, but that was not the case.

Lousy auto feed
I always have to manually feed line from the spool. That sucks.

I recently purchased this replacement spool & line. I thought I only received one spool in my pack, but I did get 2 spools in my pack. Sorry about that first review. This is a good product

My trimmer does not auto feed and the cap frequently flys off and the trimmer line gets all tangled and ruins the whole spool

The problem is the string
This is the best weedeater/edger/mower that I know of. The problem is the string does not last long at all anymore. Is there a stronger/thicker string that will last on the 20v 3 in one?
