0.065" Line String Trimmer Autofeed Replacement Spool,AF-100 Line String Trimmer, 30ft Weed Eater Spool Replacement Spool for String Trimmer, for Black and Decker Models (10 Spools+2 Caps)12 Pack

What It Is

This is a 12-pack of pre-wound 0.065-inch diameter autofeed replacement spools (30 feet of line each) designed for string trimmers. It’s meant for light to medium-duty trimming around edges, fences, and flower beds, not for heavy brush or thick weeds.

Fitment & Compatibility

Before buying, check three things:

• Line diameter: 0.065" is standard for electric and small gas trimmers. If your trimmer requires 0.080" or 0.095" line, these spools will be too thin and may break or feed poorly.
• Spool design: These are AF-100 style spools. They fit many Black+Decker models (e.g., GH900, GH910, GH1000, LST136, NST2118) and some Craftsman, Ryobi, and Weed Eater trimmers. Confirm your model uses a top-loading spool with a center shaft and two retaining caps.
• Caps included: The kit comes with 2 extra caps (top and bottom). If your trimmer uses a unique cap shape or locking mechanism, these may not seat securely.

Measure your existing spool’s width and hub diameter. If it’s not a standard AF-100 shape, it won’t fit.

Key Things to Know

• Quality vs. OEM: Line is slightly thinner than genuine Black+Decker spools and may wear faster in rocky or abrasive conditions. Fine for grass, not for concrete edges.
• Installation: Snap the spool into the trimmer head, thread the line through the eyelet, and press the cap on. No winding required. Takes about 30 seconds per spool.
• Autofeed reliability: The bump-feed mechanism works well, but occasional line tangling or jamming can happen if the cap isn’t fully seated. Double-check alignment.
• Value: At ~$1.15 per spool, it’s much cheaper than buying single OEM spools ($4–$8 each). For frequent trimming, this pays off quickly.

Should You Buy It

Buy this if you own a compatible Black+Decker (or similar) trimmer and do regular lawn edging—not heavy brush cutting. The lower cost per spool makes it ideal for high-use homeowners who want a bulk supply. Skip it if you need thicker line for tough weeds or if your trimmer uses a proprietary spool design.
