SF-080 Replacement Spool，GH3000 Trimmer Spools, Auto Feed Replacement Spools,20-Foot, 0.08-Inch, Auto Feed,Compatible with Black and Decker Weed Eater LST540 LST540B SF-080-BKP String Trimmer- 7 Pack

What It Is

A pack of 7 auto-feed replacement spools pre-wound with 20 feet of 0.08-inch trimmer line. Designed for Black+Decker and Weed Eater string trimmers that use the SF-080-BKP spool system—ideal for light trimming around edges, fences, and flower beds.

Fitment & Compatibility

• Exact spool type: SF-080 (also labeled SF-080-BKP). This is the OEM equivalent for Black+Decker LST540, LST540B, GH3000, and most 20V/40V string trimmers that use a bump-feed or auto-feed spool.
• Check before buying: Remove your current spool and confirm the part number is SF-080 or SF-080-BKP. Also verify your trimmer uses a 0.080-inch line (not 0.065 or 0.095). This spool will not fit trimmers with a fixed-line head or those requiring a different spool shape (e.g., AFS-100 or AF-100).
• Measurements: Line diameter is 0.08 inches (2.0 mm). Spool diameter is ~2 inches. Do not force into a smaller housing.

Key Things to Know

• Quality vs. OEM: These aftermarket spools are slightly thinner plastic than the genuine Black+Decker spools, but most users report they feed reliably. A few note the line can jam if the spool isn’t fully seated.
• Installation: Very easy—just remove the old spool, align the line ends with the eyelets, and push the spool into the head until it clicks. No tools needed.
• Common gotcha: The line may be wound looser than OEM. Before first use, pull a few inches of line out and trim to the blade’s cutting edge. Overly long line can cause the auto-feed to jam.
• Pack value: 7 spools at this price is a good deal if you trim often—each spool lasts about 2-3 standard yard trims.

Should You Buy It

Buy this if you own a Black+Decker or Weed Eater trimmer that uses the SF-080 spool and want a budget-friendly bulk pack for regular light trimming. Skip it if you need heavy-duty line for thick brush or if your trimmer uses a different spool shape (e.g., AFS-100).
