GreatBuddy 3 Pack AF-100 Weed Eater String Compatible with Black Decker Wacker String Trimmer Line, 30ft, 0.065 Inch

What It Is

This is a 3-pack of 0.065-inch diameter, 30-foot total replacement trimmer line specifically designed for lightweight, electric string trimmers—most commonly Black+Decker models. It’s for light-duty trimming of grass and small weeds, not heavy brush.

Fitment & Compatibility

• Line diameter: 0.065 inch. This fits most Black+Decker and other electric trimmers that accept 0.065-inch line. Do not use in trimmers requiring 0.080-inch or thicker line—it will snap or fail to feed.
• Model check: Compatible with Black+Decker models like GH900, GH1000, LST136, LST300, LST400, and many others using the AF-100 spool system. Also fits some Craftsman, Weed Eater, and Ryobi electric trimmers with the same spool type.
• OEM vs aftermarket: This is an aftermarket replacement, not an OEM Black+Decker part. It’s designed to work in the AF-100 spool, but fitment may vary slightly.
• What to verify: Before buying, check your trimmer’s manual or existing spool for “0.065 inch” or “AF-100” markings. If your spool has a different size or design, this won’t work.

Key Things to Know

• Quality: Users report the line is flexible and feeds smoothly, but it’s thinner than OEM line—expect shorter lifespan per spool if trimming tougher weeds.
• Installation: Easy to install if you follow the included instructions. No tools needed. The line comes pre-wound on three spools, so you just swap the old spool.
• Common gotcha: The line may be slightly softer than OEM, making it more prone to breaking if you hit hard surfaces (rocks, concrete) at high speed. Avoid contact with fences or curbs.
• Value: At ~$5.68 for 90 total feet, it’s a budget-friendly bulk option compared to single OEM spools.

Should You Buy It

Buy this if you have a compatible lightweight electric trimmer (especially Black+Decker) and want an affordable, easy-to-install replacement for routine grass trimming. Skip it if you need heavy-duty line for thick weeds or brush—go with 0.080-inch or larger instead.
