10 Pack Weed Eater String Compatible with Black+Decker, AF-100 0.065" Weed Wacker String Refill 240ft Automatic Feed String Trimmer Replacement Spool Line for Black&Decker(8 Spool+2 Cap+2 Spring)

What It Is

This is a 10-pack replacement trimmer line set for Black+Decker string trimmers using the AF-100 automatic feed spool system. It includes 8 pre-wound spools (0.065-inch diameter, 240 feet total), plus 2 extra caps and 2 springs for maintenance.

Fitment & Compatibility

• Line diameter: 0.065 inches (1.65mm) – fits Black+Decker models that require this thin line (e.g., GH900, GH1000, LST136, LST220). Check your manual or existing spool for line size; 0.065” is for light-duty trimming, not heavy weeds.
• Spool type: AF-100 compatible – fits most Black+Decker automatic feed trimmers. Not compatible with manual feed or bump-feed models (e.g., GH610, GH800 use different spools).
• Brand: Aftermarket, not OEM Black+Decker. Verify your trimmer model number (on underside of motor housing) against “AF-100” in the compatibility list.
• What to check: Your current spool must match the AF-100 shape and cap retention style. If your original spool is a different part number (e.g., AFS-100 or AF-200), this won’t fit.

Key Things to Know

• Installation: Drop-in ready – no winding required. Remove old spool, snap in new one, thread line through eyelet. The extra caps and springs help if originals wear out.
• Line quality: 0.065” is thin and flexible; good for grass and light weeds but snaps easily on thicker brush or against fences. Not for heavy-duty use.
• Common gotcha: The line may be slightly stiffer than OEM, causing occasional jamming in the feed mechanism. If your trimmer has a “bump” feed head, this spool type may not work correctly.
• Value: 8 spools for ~$9.50 is cheaper per spool than buying OEM singles, but you’re locked into one line diameter.

Should You Buy It

Buy this if you have a Black+Decker AF-100 compatible trimmer used for light lawn maintenance (grass, small weeds) and want a bulk, no-hassle replacement. Skip it if you need a thicker line (0.080” or 0.095”) for heavy-duty trimming, or if your trimmer uses a bump-feed or manual-feed spool system.
