AF-100 0.065 in. x 30 ft. Replacement Single Line Automatic Feed Spool AFS Compatible with Black Decker Electric String Grass Trimmer/Lawn Edger/Mower 3 Spools & 1 Cover Cap

What It Is

This is a three-pack of replacement trimmer spools (0.065-inch line, 30 feet each) plus a cover cap, designed for automatic-feed Black+Decker electric string trimmers, edgers, and mowers. It’s a direct drop-in replacement for the OEM AF-100 spool, letting you refill without measuring or cutting line.

Fitment & Compatibility

Before buying, check these:

• Model compatibility: Works with most Black+Decker electric trimmers that use the AF-100 spool (e.g., GH900, GH910, GH912, GH1000, LST136, LST220, LST300). Not for gas trimmers or other brands.
• Line size: 0.065-inch diameter is standard for light-duty electric trimmers. If your machine calls for 0.080-inch or 0.095-inch, this spool won’t fit the head.
• Spool width & shape: The AF-100 spool is a single-line, automatic-feed design (not bump-feed). The included cover cap snaps onto the spool housing—verify your trimmer uses a cap, not a screw-on retainer.
• OEM vs aftermarket: This is a third-party replacement, not Black+Decker branded. Reviews note it fits snugly but may require slight trimming of the line end to feed smoothly.

Key Things to Know

• Quality: Line is thinner than OEM (0.065-inch vs some 0.080-inch factory spools). It’s fine for light weeds and grass, but will wear faster on thicker brush or rocky edges.
• Installation: Easy—pop off old spool, line up the arrow, push in new spool, snap cap. Some users report the cap fits loose or cracks after a few uses; keep the original cap as a backup.
• Automatic feed vs bump-feed: The AF-100 feeds automatically when you start the trimmer. If you prefer bump-feed (tap head to release line), this spool won’t work—it’s strictly auto-feed.
• Line length: 30 feet per spool is standard, but you can wind less if your trimmer head has a smaller capacity. Overfilling can cause jams.

Should You Buy It

Buy this if you own a compatible Black+Decker electric trimmer, want a quick no-measure refill, and don’t need heavy-duty line for thick weeds or edging against concrete. It’s a budget-friendly three-pack that saves time, but skip it if your trimmer uses 0.080-inch line, bump-feed, or a different spool shape.
