Weed Eater String Compatible with Black+Decker, 30ft 0.065" (AF-100) Autofeed String Trimmer Line Replacement Spool for Black+Decker Trimmer Line, 6 Spools & 1 Cap

What It Is

This is a 6-pack of 0.065-inch diameter autofeed trimmer line spools (30 feet per spool) plus a replacement cap, designed for Black+Decker string trimmers that use the AF-100 style spool system. It’s a direct drop-in replacement for worn-out line.

Fitment & Compatibility

• Line diameter: 0.065 inch – only use on trimmers that accept this size (check your manual or current spool label). Thicker line may jam or overload the motor.
• Spool type: AF-100 (also labeled as AFS-100, AFS-100-2, or AF-100-1). Fits most Black+Decker cordless and electric trimmers (e.g., LST136, LST300, GH900, GH1000, NST1118). Does not fit older models using different spool designs.
• OEM vs aftermarket: This is a generic replacement, not made by Black+Decker. It works, but the cap may be slightly looser or tighter than OEM – verify your existing cap is in good shape.
• Measurement check: Measure your current spool’s diameter (about 2 inches) and line thickness (0.065 inch) before buying. If your trimmer uses 0.080 or 0.095 line, this won’t work.

Key Things to Know

• Installation difficulty: Easy – snap off old spool, remove cap, line up new spool’s arrows with housing tabs, push in, and snap cap. No tools needed.
• Autofeed mechanism: Works best if you pull exactly 3–4 inches of line through the eyelet after installation. Too much line causes jamming.
• Line quality: The line is standard round nylon – fine for light weeds and grass, but will wear faster on heavy brush or against fences. Not reinforced or twisted.
• Common gotcha: The included cap may not fit all models snugly. If your existing cap is in good shape, reuse it for a better seal.

Should You Buy It

Buy this if you have a compatible Black+Decker trimmer and want a cheap, convenient bulk supply of line that saves you from buying single spools. It’s right for light to medium trimming around lawns, gardens, and sidewalks. Skip it if you need heavy-duty line for thick brush or want OEM fit confidence – go with a genuine Black+Decker spool instead.
