SB00L00 Spool Replacement Bump Trimmer Head 2926507 Compatible with Greenworks ST40L00 ST60V ST60L210 ST60L00 ST60B00 80V ST80L200 Front Mount String Trimmer Weed Wack,Pre-Wound 0.080" 17Ft Dual Line

What It Is

This is a pre-wound replacement spool and bump head assembly for Greenworks 40V and 80V front-mount string trimmers. It replaces the OEM part SB00L00 (also labeled 2926507) and includes 17 feet of 0.080-inch dual line, ready to install without winding.

Fitment & Compatibility

• Exact models: ST40L00, ST60V, ST60L210, ST60L00, ST60B00, ST80L200 – all front-mount (not curved-shaft or rear-mount) trimmers.
• Check your trimmer head: If your existing head says “SB00L00” or “2926507” on the label, this is a direct swap. If not, measure the spool diameter (approx. 2.5 inches) and line exit slots – this only fits that specific bump-feed design.
• OEM vs aftermarket: This is a third-party replacement, not genuine Greenworks. It may fit physically but can vary in plastic quality and bump-feed reliability.
• Do not buy if: Your trimmer uses a different line size (e.g., 0.065 or 0.095 inch) or has a rear-mount motor – those use a completely different head.

Key Things to Know

• Pre-wound saves time – no winding required, but the line is only 0.080 inch thick, which is fine for light grass but may break faster on thick weeds.
• Bump-feed mechanism can be finicky – several reviews mention the head jams or doesn’t advance line consistently, especially with thicker or damp line.
• Installation is simple – unscrew the old head, snap this one on, and tighten the cap. No tools needed, but ensure the trimmer is off and battery removed.
• Line length is short – 17 feet total (8.5 feet per side) means you’ll replace the spool more often than with a larger-capacity head.

Should You Buy It

If you own one of the listed Greenworks front-mount trimmers and need a quick, no-wind replacement for light trimming, this spool works in a pinch. But if you value consistent bump-feed or heavier-duty cutting, spend a few dollars more for an OEM Greenworks SB00L00 spool – the aftermarket reliability is hit-or-miss at this price.
