THTEN SF-080 String Trimmer Spool Line Compatible with Black and Decker SF-080-BKP 20ft 0.080" GH3000 LST540 GH3000R LST540B Weed Eater Auto Feed Single Line with 90583594 Cap Covers Parts

What It Is

This is a replacement spool and cap set for Black+Decker and Weed Eater string trimmers, pre-wound with 20 feet of 0.080-inch trimmer line. It’s designed for light-duty trimming around edges, fences, and flower beds.

Fitment & Compatibility

• Exact models: SF-080-BKP, GH3000, GH3000R, LST540, LST540B, and other Black+Decker/Weed Eater trimmers using the 90583594 cap.
• Line diameter: 0.080 inch – verify your trimmer’s manual or existing spool for this size. Using larger line can overload the motor or jam the feed.
• Cap style: The included cap covers snap onto the spool; confirm your trimmer uses a push-button or twist-lock cap (this kit replaces the original cap).
• OEM vs aftermarket: This is an aftermarket replacement, not Black+Decker OEM. It fits the listed models but may have slightly looser tolerances.

Key Things to Know

• Quality: Pre-wound spool saves time, but the line may be slightly stiffer than OEM. Most users report it feeds reliably after a short break-in.
• Installation: Remove old spool, insert new one, align cap tabs with trimmer head slots, and push until it clicks. No tools needed.
• Common gotcha: If the line doesn’t advance, check that the cap is fully seated and the line isn’t pinched under the cap edge. A gentle tap on the ground usually triggers auto-feed.
• Durability: Suitable for light grass and weeds. For thick brush or heavy use, consider a larger line diameter or heavier-duty trimmer.

Should You Buy It

Buy this if you own one of the listed Black+Decker or Weed Eater trimmers and want a quick, no-fuss replacement spool. It’s a good value for light trimming, but skip it if you need a heavy-duty line or an exact OEM fit.
