Overview
This aftermarket replacement spool comes pre-loaded with trimmer line at the correct diameter and winding pattern for your trimmer. When the original spool runs empty or the line becomes brittle from UV exposure, swapping in a fresh spool is faster than re-winding. The pre-wound design ensures consistent bump-feed performance from the start.
Key specifications

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
Turn off the trimmer and remove the spool cover by pressing in the retaining tabs. Remove the old spool and wipe out the housing. Insert the replacement spool, thread the line ends through the eyelets, and snap the cover into place. Test the bump-feed mechanism by tapping the head and pulling the line.
Common questions
Q: Will this 6PC SB00L00 Dual Replacement Spool STF402 fit my Greenworks ST80L210 front-mount trimmer, or is it only for the SB00L00 head?
Yes, this spool is made for the Greenworks front-mount string trimmer system used on the ST80L210 and also fits models listed under SB00L00, ST80L00, STBA80L210, ST60B00, STBA60B411, ST60B210, and ST60B211. If your trimmer uses the SB00L00/STF402 dual-line spool style, these replacements should install correctly.
Q: How do I install one of these SB00L00 dual replacement spools without tangling the line?
First, power off the trimmer and remove the battery, then open the trimmer head and take out the old spool. Drop the new spool in the same orientation as the original, feed the line ends through the eyelets, and make sure the line is seated in the guide slots before closing the cap so it feeds smoothly on startup.
Q: Are these dual spools better for regular grass trimming, or can they handle thicker weeds on my ST60B211 straight shaft trimmer too?
These dual-line spools work well for normal grass trimming and light to moderate weed growth, especially on the ST60B211 and similar straight shaft Greenworks models. For best performance on thicker weeds, keep the line length correct, avoid forcing the head into dense stalks, and replace the spool once the line gets too short or starts feeding unevenly.
