Overview
Designed as a plug-and-trim aftermarket replacement, this pre-wound spool fits directly into the trimmer head without any custom winding. Factory spools eventually run out, and hand-winding bulk line can be time-consuming and prone to tangles. This replacement spool provides properly wound line that feeds smoothly from the first tap.
Key specifications
- Pre-wound replacement trimmer spool
- Line length per spool: 16 ft
- 4-pack quantity

Compatibility
This spool is designed for Kobalt string trimmers as listed above. Confirm the spool part number, line diameter, and trimmer model before ordering to ensure a proper fit.
Installation notes
Disconnect the battery or unplug the trimmer. Remove the bump knob or spool cover by pressing the release tabs. Lift out the used spool, insert the new one with the line routed through the exit holes, and replace the cover. Pull the line to confirm smooth feed before starting.
Common questions
Q: Will this 0.080” 16ft replacement spool fit my Kobalt 24V KST 2224B-03, or is it only for the KLS 124-03 head?
Yes, this spool is made for the Kobalt KLS 124-03 spooled trimmer line system and is compatible with the Kobalt 24V KST 2224B-03, KST 1124B-03, and KST 2024A-03. It also replaces the AS1300 spool used on EGO 15” trimmers like the ST1500 and ST1500-S, as long as your trimmer uses that same spool style.
Q: Can I use this spool in my EGO ST1500-S even though it’s listed under Kobalt compatibility too?
Yes, this spool is designed as a replacement for the AS1300 spool, which fits EGO 15” models such as the ST1500 and ST1500-S. The key things to match are the spool type and line size—this one comes preloaded with 0.080” line and 16 ft of cutting line per spool.
Q: Do I need to rewind the line myself, or is this ready to install, and are there any tips for getting it to feed correctly?
These are replacement spools, so they come pre-wound and are ready to install in the trimmer head. When installing, make sure the line ends are routed through the eyelets cleanly and the spool is seated in the correct direction; if the line doesn’t feed smoothly, check for a twisted line end or debris inside the spool cap.
