BLACK+DECKER Trimmer Line Replacement Spool, Dual Line, AFS, .065-Inch (DF-065)

What It Is

The DF-065 is a pre-wound dual-line replacement spool for BLACK+DECKER string trimmers, designed for trimming grass and light weeds. It uses .065-inch diameter line and integrates with BLACK+DECKER’s Automatic Feed Spool (AFS) system, which advances line automatically without bumping.

Fitment & Compatibility

• Model check: Fits most BLACK+DECKER trimmers with the AFS system (e.g., GH600, LST136, NST2118). Not compatible with non-AFS models or those requiring .080 or .095 line.
• OEM vs aftermarket: This is a genuine BLACK+DECKER part. Aftermarket spools may not fit the AFS mechanism correctly.
• Measurement: Line diameter is .065 inch (1.65 mm). Spool width is approximately 1.5 inches; verify your trimmer head accepts this size.
• What to confirm: Look at your current spool or trimmer manual for “AFS” branding. If your machine has a manual-feed head, you need a different spool.

Key Things to Know

• Installation: Snap-in replacement—no tools required. Ensure the line ends are cut cleanly and the spool clicks into place. Misalignment can cause AFS to jam.
• Line quality: .065-inch line is fine for light trimming; thicker weeds may break it. Upgrade to .080 if you have heavier growth.
• AFS quirks: The auto-feed can overrun if the trimmer is used at high RPM on thick material. Briefly tap the head on the ground to reset. If feeding stops, check for debris in the spool housing.
• Length per spool: Each spool holds about 20 feet of line total (two lines). Replacement frequency depends on usage; expect 2-3 full trims per spool for a typical lawn.

Should You Buy It

Buy this if you own a BLACK+DECKER AFS trimmer and want a hassle-free, drop-in replacement with reliable auto-feed. It’s best for light-duty trimming on small to medium yards. Skip it if you need thicker line for heavy brush or own a non-AFS model—you’ll need a different spool or manual-feed line.
