DF-065 String Trimmer Replacement Spool Compatible with Black and Decker GH700 GH710 GH750,DF065 AFS Dual Line 36ft 0.065" (3Pack)

What It Is

This is a 3-pack of replacement spools pre-wound with 0.065-inch dual line trimmer string, designed for Black+Decker GH700, GH710, and GH750 string trimmers. It works with the AFS (Automatic Feed System) that advances line automatically when you tap the head on the ground.

Fitment & Compatibility

Before buying, confirm your trimmer model is exactly one of these: GH700, GH710, or GH750 (check the model number label on the trimmer’s shaft or near the handle). This spool is aftermarket, not OEM Black+Decker, but uses the same drop-in design. The 0.065-inch line diameter is standard for these models—do not use thicker line (e.g., 0.080") as it may jam the AFS mechanism. Also verify your trimmer uses the AFS bump-feed system (most GH700/710/750 do), not a fixed-line head.

Key Things to Know

• Line length & capacity: Each spool holds 36 feet of 0.065" line—enough for typical residential trimming. The 3-pack gives you 108 feet total.
• Installation: No tools needed—just remove the old spool, align the tabs, and snap the new one in. Make sure the line ends are free and not tangled before closing the head.
• Quality caution: Some users report the line can be slightly brittle compared to OEM spools, so avoid hitting hard surfaces (concrete, stones) aggressively.
• Common gotcha: If the head doesn’t advance line after installation, double-check that the spool is seated fully and the line is not pinched under the cover.

Should You Buy It

If you own a compatible Black+Decker GH700/710/750 and want a budget-friendly alternative to OEM spools, this 3-pack delivers good value for the price. It’s ideal for routine trimming on small to medium lawns—just be mindful of the line’s durability on rough terrain. For heavy-duty or commercial use, consider OEM spools or thicker line options.
