10 Pack AF-100 Replacement Spool Compatible with Black+Decker AF-100-3ZP AF-100-BKP, 30Ft 0.065" Autofeed Weed Wacker String Trimmer Spools for Black and Decker Weed Eater (8 Spool,2 Cap,2 Spring)

What It Is

This is a 10-pack of replacement autofeed spools pre-wound with 30 feet of 0.065-inch trimmer line. Designed for Black+Decker cordless and electric string trimmers that use the AF-100-style spool (including AF-100-3ZP and AF-100-BKP models). It saves you from manually winding line and gives you backup spools for the season.

Fitment & Compatibility

Before buying, confirm your trimmer uses the AF-100 spool system (not the smaller AF-50 or larger AF-200). This 10-pack includes 8 spools, 2 caps, and 2 springs—check if your trimmer’s original cap and spring are reusable (most are, but older models may need the spares). The 0.065-inch line fits standard residential trimming (light weeds, grass). Not compatible with gas trimmers, fixed-line heads, or bump-feed systems.

Check your model number on the trimmer’s label or manual. Common compatible models: LST136, LST220, LST300, GH900, GH1000, NST2118, MSC100, MSC150. If your trimmer takes a different spool (e.g., AF-100-2ZP or AF-100-4ZP), this pack works—they’re all same size, just different packaging.

Key Things to Know

• Autofeed works best with thin line – 0.065" is ideal. Thicker line (0.080") may jam in the autofeed mechanism or cause premature wear.
• Install takes 2 minutes – Remove old spool, drop in new one, thread line through the eyelet, and snap the cap back on. No tools needed.
• Not all spools are identical – Some aftermarket spools have slightly different hub depth. If the cap doesn’t click securely, you may need to trim the line a bit shorter or swap the spring.
• Line is pre-wound evenly – Save time vs. hand-winding. But if the line is tangled on arrival, unwind and re-wind manually.

Should You Buy It

If you own a compatible Black+Decker autofeed trimmer and want a season’s worth of spools without stopping to rewind, this 10-pack is a solid value. The 4.6-star rating reflects consistent fit and reliable autofeed performance. Skip it if you prefer bump-feed heads or use thicker line for heavy brush.
