Black+Decker Genuine OEM Authentic Weed Eater String, Trimmer Line Replacement Spool, Autofeed 30 ft, 0.065-Inch, 2-Pack (AF-100-2)

What It Is

This is a genuine OEM replacement spool pre-wound with 30 feet of 0.065-inch trimmer line for Black+Decker weed eaters with an automatic feed system. Designed for light to medium trimming around lawns and gardens.

Fitment & Compatibility

• Fits most Black+Decker string trimmers with the AF-100 (AutoFeed) spool system, including models like GH3000, GH3100, GH500, and GH900.
• Not compatible with manual-feed, bump-feed, or fixed-line heads—only works with AutoFeed models.
• Check your trimmer’s manual or existing spool for “AF-100” marking. If your current spool has a metal pin or requires bumping to advance line, this won’t fit.
• OEM part (Black+Decker genuine), not aftermarket—guaranteed fit for listed models.
• Line diameter is 0.065-inch (1.65mm)—do not substitute thicker line; it will jam the auto-feed mechanism.

Key Things to Know

• Installation is tool-free: Remove old spool, snap in new one, thread line through the eyelet. Takes under 2 minutes.
• Auto-feed works reliably when line is properly seated—no bumping required. Line advances automatically when you throttle up.
• Line is thin (0.065")—great for grass and small weeds, but snaps quickly against thick brush or rocks. Not for heavy-duty clearing.
• 2-pack saves money vs buying singles. Each spool lasts roughly 2-3 residential trims depending on usage.

Should You Buy It

Buy this if you own a compatible Black+Decker AutoFeed trimmer and want a hassle-free, drop-in replacement that works every time. It’s ideal for homeowners maintaining a typical lawn—just avoid it for heavy brush or commercial use where thicker line is needed.
