Overview
Keep your string trimmer ready for action with this pre-wound replacement spool. It is built to the same dimensions as the OEM spool, so it drops right into the trimmer head with no modifications. Aftermarket spools provide the same cutting performance as factory originals at a better value.
Key specifications
- Pre-wound replacement trimmer spool
- 6-pack quantity

Compatibility
This spool is designed for Greenworks string trimmers as listed above. Confirm the spool part number, line diameter, and trimmer model before ordering to ensure a proper fit.
Installation notes
Remove the spool cover from the trimmer head. Extract the old spool and clean out any grass or debris. Insert the new pre-wound spool, feed the line ends through the guide holes, and reattach the cover. Verify the line extends the correct length before trimming.
Common questions
Q: Will this 6-pack spool fit my Greenworks 80V ST80L210 and the 40V 2111802 trimmer, or is it only for one voltage platform?
Yes, these replacement spools are made to fit both the Greenworks 40V 15” Straight Shaft String Trimmer 2111802 and the listed 80V 16” models, including ST80L210. They’re also compatible with 2100102, 2102602, ST80L00, GST80321, ST80L2510, and STBA80L210, so fitment is based on the trimmer model number, not just the battery voltage.
Q: How do I install one of these replacement spools on my Greenworks 2102602 without tangling the line?
Remove the battery first, then open the trimmer head and take out the old spool. Drop the new pre-spooled cartridge in the same orientation as the original, feed the line ends through the eyelets if needed, and make sure the cap snaps back on securely so the line can advance smoothly.
Q: My Greenworks GST80321 keeps breaking line quickly—will these spools help, and is there anything I should do to make them last longer?
A properly matched spool helps the trimmer feed line more consistently, which can reduce binding and premature snapping compared with a poorly fitting spool. To extend line life, avoid hitting concrete, chain-link fencing, and thick woody stems, and if the line seems brittle, soaking it in water for several hours can help restore flexibility.
