Replacement Spool for Black+Decker 12 Pack Trimmer String 0.065" AF-100 Autofeed Replacement Spools(12 Spool+4 Caps)

What It Is

This is a 12-pack of replacement spools pre-wound with 0.065-inch diameter string, designed for Black+Decker AF-100 Autofeed trimmer heads. It’s for string trimmers that use the automatic line-advance system—no bumping required.

Fitment & Compatibility

• Exact fit: Only for Black+Decker trimmers with the AF-100 Autofeed head (common on models like GH900, GH1000, LST136, NST2118). Check your trimmer’s model number—look for “AF-100” on the head itself.
• String size: 0.065-inch diameter—won’t fit heads designed for 0.080-inch or larger line. Do not use in manual-feed or bump-feed heads; it won’t advance.
• Included caps: Each spool comes with a cap (4 extra caps total). Make sure your trimmer uses the same cap retention style (twist-lock or snap-on). Spools are aftermarket, not OEM Black+Decker, but fit OEM heads.
• Pre-wound: Ready to install—no winding required. Just remove old spool, drop in new one, and thread line through eyelet.

Key Things to Know

• Installation: Easy—pop off the head cover, remove empty spool, replace with new one, and snap cover back on. No tools needed.
• Autofeed reliability: Works as intended on AF-100 heads, but if your trimmer has a clogged or worn feed mechanism, it may jam. Clean the head before installing.
• String quality: 0.065-inch line is lightweight—great for light trimming (grass, weeds), but will snap quickly on thick brush or against fences. Not for heavy-duty use.
• 12-pack value: Good for frequent use (e.g., large yards or multiple trimmers). Each spool lasts about 15-30 minutes of continuous trimming depending on debris contact.

Should You Buy It

Buy this if you own a Black+Decker trimmer with an AF-100 head and need a steady supply of pre-wound spools for light-to-medium trimming. It’s a solid, no-fuss value for regular maintenance—just skip it if you need thicker line for heavy brush or have a different feed system.
