Overview
This pre-wound replacement spool drops directly into compatible string trimmers, eliminating the hassle of hand-winding line. Worn or empty spools leave trimmer owners without a cutting edge mid-job. Keeping spare aftermarket spools on hand ensures minimal downtime and consistent line feed during yard work.

Common questions
Q: Will this 6PC SF-080 spool set fit my Black+Decker GH3000R and does the included cap replace part 90583594N?
Yes, this replacement set is made for the Black+Decker GH3000, GH3000BM, GH3000R, LST540, and LST540B, and it also matches spool part 90588459N / SF-080-BKP. The included cap is the 90583594N style, so it should fit those compatible trimmer heads as a direct replacement.
Q: Do these SF-080 spools come pre-wound, and is there anything special I need to do when installing them on a GH3000?
These spools are pre-wound, so installation is usually just a matter of removing the old cap, lifting out the old spool, and dropping the new SF-080 spool into place with the line fed through the eyelets. Make sure the line is seated correctly and the cap snaps on fully, because a misaligned spool or loose cap can cause poor line feed.
Q: My LST540 keeps jamming or burning through line quickly—will replacing both the spool and cap help, and how can I make the new ones last longer?
If your current spool is worn, warped, or the cap no longer holds it securely, replacing both parts can help restore smoother auto-feed performance. To extend line life, avoid forcing the trimmer into thick brush, keep the cap free of packed grass and debris, and check that the spool rotates freely each time you reload or replace it.
