Frequently Asked Questions

  • What is a spool cap cover used for?

    The spool cap cover is what secures the trimmer spool in place so your trimmer functions properly and efficiently. It also protects the spool and prevents weeds/grass from getting caught in the mechanism and causing damage or interrupting your yardwork.

  • What is the spool cap made of?

    The spool cap cover is made of high impact ABS for strength and durability.

  • Do I have to purchase this separately when I buy a trimmer?

    Each trimmer comes with the spool cap cover appropriate for that model. This package is available for any customer who has lost or broken their spool cap cover.

  • What trimmer/edger models will this spool cap (WA0037) cover fit?

    This spool cap cover fits the WG168, WG184, and WG191 battery-operated trimmers.

  • Will this spool cap (WA0037) cover fit the WG190?

    This spool cap cover will not fit the WG190.

    A convenient spool and spool cap combo pack for the WG190 is available under Accessories.

  • Can I use the trimmer without it?

    Since the spool cap cover keeps your spool in place while working, you will not be able to trim without it.

  • Are there any precautions I should follow?

    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.

Rated 5 out of 5 by from Great trimmer! I previously bought the 56V trimmer for my husband. He absolutely loves it. The spool cap broke when it met with a high concrete curb. Nothing wrong with the cap — concrete will always win the battle. Great products!

Rated 5 out of 5 by from Finally..... I have been waiting several months to get these replacement spool cap covers. The original cap broke in October and there were no parts available. I kept checking the website and it always seemed to say out of stock. Finally ordered some in March and they look and feel solid. I have trimmed a few times and they seem to hold up well.

Rated 4 out of 5 by from great Well what can I say, its a cap for my trimmer.The original one wore out and cracked, which should have not. But the new cap works fine, lets see how long this one lasts. But I have to be fare about this other trimmers have the same problem. Seems like an engineering flaw to me. Material needs to be made thicker so that it will not wear out. But it works fine for now.

Rated 3 out of 5 by from I ordered the wrong covers. It is too big for my trimmer.
Date published: 2019-07-02
Rated 3 out of 5 by from stock up on these although the worx weed wacker is probably the best on the market, they skimped when it came time to make the spool cap cover. I have owned my trimmer for 2 years now, the 56v battery holds its charge long enough to trim half of my 1/8 acre yard, and has lasted this long, just keep it on the charger. The string release works well as long as you have wound the line properly. But I have gone thru 6 cap covers, and they are not always available thru worx, and can be hard to find any where else... including ebay. so I recommend ordering several at a time.
