SF-080 Replacement Spool, SF 080 trimmer,20ft 0.080 inch for Black and Decker GH3000 LST540 LST540B GH3000R SF-080-BKP Auto Feed Spool Single Line Trimmer,GH3000 trimmer spool replacement (8 Pack)

What It Is

This is an 8-pack of replacement spools pre-wound with 20 feet of 0.080-inch trimmer line, designed for Black+Decker cordless and electric string trimmers that use the SF-080 Auto Feed system. It eliminates manual line winding—just drop in and go.

Fitment & Compatibility

Before buying, confirm your trimmer model uses the SF-080 spool system. Compatible with: Black+Decker GH3000, LST540, LST540B, GH3000R, and any trimmer that accepts the OEM SF-080-BKP spool.
Check:

• Spool diameter: Must match your trimmer’s spool housing (typically ~2.5 inches).
• Line thickness: 0.080-inch line; if your trimmer requires 0.065 or 0.095, this won’t fit.
• Auto Feed mechanism: This spool uses a bump-feed head; not compatible with manual-feed or fixed-line heads.
• OEM vs aftermarket: Aftermarket spool; fits OEM housing but may have slightly looser tolerances.

Key Things to Know

• Installation: Very easy—pop off the old spool, align the tabs, and snap in. No tools needed.
• Line length: 20 feet per spool is adequate for most residential yards, but heavy weed trimming may deplete it faster.
• Common gotcha: The pre-wound line can sometimes tangle on the first use—pull out a few inches and let the bump feed work to release it smoothly.
• Quality: 4.4 stars from 353 reviews indicates consistent performance, but some users report the line breaks more easily than OEM on thick weeds.

Should You Buy It

If you own a compatible Black+Decker trimmer and want a convenient, no-wind solution at a low per-spool cost (about $1.28 each), this 8-pack is a solid value. It’s best for light-to-medium trimming; for heavy-duty brush or frequent use, consider OEM spools or thicker line options.
