SB00L00 Trimmer Replacement Cover Cap Compatible with Greenworks STG401 ST60V ST60V-T0 ST60L210 ST60L00 ST60B00 80V ST80L200 Front Mount String Trimmer,with Part Bump Knob & Spring(5Pack)

What It Is

This is a 5-pack replacement trimmer head cover cap assembly for Greenworks front-mount string trimmers, including the bump knob and spring. It protects the trimmer head and houses the bump-feed mechanism that advances the cutting line.

Fitment & Compatibility

Before buying, confirm your model is listed: Greenworks STG401, ST60V, ST60V-T0, ST60L210, ST60L00, ST60B00, or ST80L200. These are all front-mount (straight shaft) trimmers. If you have a curved-shaft or rear-mount model, this cap will not fit. The cap is not an OEM Greenworks part but an aftermarket replacement; check that your existing bump knob and spring are worn or broken to justify the 5-pack. No deck size or measurement checks needed—fitment is model-specific.

Key Things to Know

• Quality: Several users report the plastic is slightly less durable than OEM, but the 5-pack provides spares for the price of a single OEM cap.
• Installation: Simple—remove the old cap, swap the spring and knob, and snap the new cap into place. No tools required.
• Gotcha: The bump knob may feel looser or require a firmer tap to advance line compared to the original. Test on a spare cap first.
• Pack size: 5 caps means you have backups for multiple trimmers or future wear, but you only get one bump knob and spring per pack (not 5 of each).

Should You Buy It

Buy this if you have a compatible Greenworks front-mount trimmer and want an affordable way to replace a worn or broken cap and bump-feed assembly, especially if you own multiple trimmers or anticipate future breakage. Skip it if you prefer OEM parts for guaranteed fit and feel, or if you only need a single replacement.
