Weed Eater String Compatible with Black+Decker, AF-100 0.065" Weed Wacker String Refill 360ft Automatic Feed String Trimmer Replacement Line Spool for Black&Decker (12Spools + 3Caps+3Springs)

What It Is

This is a 0.065-inch diameter weed eater string replacement kit for automatic-feed trimmer heads. It includes 12 pre-wound spools, 3 replacement caps, and 3 springs—designed for frequent users who need quick reloads without winding line by hand.

Fitment & Compatibility

• Line diameter: 0.065" (1.65 mm). Only use this size if your trimmer head is rated for 0.065" or thinner. Using thicker line can damage the head or motor.
• Brand/model: Specifically fits Black+Decker trimmers that use the AF-100 automatic feed spool system (common on models like GH900, GH1000, LST136, LST220). Also works with some Weed Eater, Craftsman, and Ryobi trimmers that share the same spool design.
• OEM vs aftermarket: This is a third-party replacement, not official Black+Decker. The spools, caps, and springs are direct fit for AF-100 heads, but check that your trimmer uses a bump-feed (not manual or fixed-line) head.
• What to check: Remove your current spool. If it has a single line slot and a spring-loaded cap, it’s likely compatible. Measure the spool diameter (should be ~2.5") and confirm the cap snaps on securely.

Key Things to Know

• Installation difficulty: Very easy. Pop off the old spool cap, swap the spring if needed, drop in a new spool, and snap the cap back. No winding required.
• Line quality: The 0.065" line is thinner than standard 0.080" or 0.095" line, so it’s best for light-duty trimming (grass, weeds). It will snap faster on thick brush or against hard surfaces.
• Common gotcha: The included caps and springs may be slightly looser than OEM parts. If the cap pops off during use, try reusing your original cap/spring instead.
• Value: 12 spools at ~$1.42 each is cheaper than buying individual packs. Good for frequent trimming on smaller yards.

Should You Buy It

Buy this if you own a Black+Decker or compatible trimmer with an AF-100 head and need a bulk supply of pre-wound spools for light to medium trimming. Skip it if you trim heavy brush, want a thicker line, or prefer OEM parts—the thinner line and slightly loose caps may not suit heavy-duty use.
