24 Pack Weed Eater String Compatible With Black and Decker Weed Wacker, AF-100 String Trimmer Line, 0.065'' 30FT Automatic Feed Trimmer Weed Eater spool, Replacement Spool Refills (20XSpools, 4Xcaps)

What It Is

This is a 24-pack of replacement trimmer line spools and caps, pre-wound with 0.065-inch diameter weed eater string. Designed for automatic feed trimmers, it’s a bulk refill set for Black+Decker weed wackers (and compatible AF-100 models) that saves you from manually winding line.

Fitment & Compatibility

• Brand & Model Fit: Officially listed as compatible with Black+Decker weed wackers using the AF-100 automatic feed spool system. Check your trimmer’s model number – if it uses a 0.065-inch line and a bump-feed or automatic-feed spool with a center post, it likely fits.
• Line Diameter: 0.065 inches (standard for light-duty trimming). Verify your trimmer’s manual – using a thicker line can jam the feed mechanism or overload the motor.
• Spool Design: Pre-wound spools with a center post. Measure your existing spool’s width and post diameter. The included caps (4x) fit this specific spool design – not universal.
• OEM vs Aftermarket: Aftermarket replacement. May not fit all Black+Decker models – especially older or non-AF-100 series. Check your model number against the seller’s list before buying.

Key Things to Know

• Pre-wound convenience: Spools come ready to install – no winding needed. Just drop in, thread the line through the eyelet, and snap the cap on.
• Line quality: 0.065-inch nylon line is standard for light grass and weeds. It’s not heavy-duty – expect faster wear on thick brush or against fences.
• Pack value: 20 spools + 4 caps for ~$18 is a solid per-spool price. But you only get 4 caps – if you lose or break caps, you’ll need extras.
• Installation tip: Match the spool’s direction arrows to your trimmer’s rotation. Wrong direction can cause line not to feed or snap immediately.

Should You Buy It

If you own a Black+Decker AF-100 or compatible automatic-feed trimmer and go through line quickly (weekly trimming, large yards), this bulk pack saves money and time. Skip it if you need heavy-duty line for thick weeds or have a different brand/model – fitment isn’t universal.
