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 spool set for Black+Decker automatic-feed string trimmers, using 0.065-inch diameter weed wacker line. It includes 8 pre-wound spools (240ft total), plus 2 spare caps and 2 springs, designed for light-to-medium trimming around lawns, gardens, and walkways.

Fitment & Compatibility

• Designed for Black+Decker models using AF-100 style spools (common on GH900, GH1000, NST2118, and many 20V/40V trimmers). Check your trimmer’s manual or existing spool for “AF-100” marking.
• Line diameter is 0.065 inches – only fits trimmers that accept this thin line. Do not use on heavy-duty trimmers requiring 0.080” or 0.095” line.
• Not compatible with DeWalt, Craftsman, Ryobi, or other brands unless they explicitly use AF-100 spools (rare). Verify spool shape and spring location matches your trimmer head.
• Includes spare caps and springs – these are common wear parts. Ensure your trimmer head uses the same cap design (push-to-release or twist-lock) before assuming fit.

Key Things to Know

• Pre-wound spools save time – no manual winding needed. Just load, thread through the eyelet, and go. Each spool holds ~30ft of line.
• Line is thinner than OEM – 0.065” vs some Black+Decker originals at 0.070”. This reduces cutting power on thick weeds but improves feed reliability and reduces breakage.
• Automatic feed works best with line cut at correct angle – trim the line to a sharp point before first use, or it may jam. Replace the spring if feed becomes erratic.
• Price per spool is ~$1.19 – far cheaper than buying individual OEM spools ($4-6 each). Great value if you trim frequently or have multiple Black+Decker trimmers.

Should You Buy It

Buy this if you own a Black+Decker trimmer that uses AF-100 spools and want an affordable, ready-to-use refill pack for light residential trimming. It’s a smart choice for frequent users who don’t mind slightly thinner line, but skip it if you need heavy-duty cutting or if your trimmer requires a different spool design.
