Greenworks 0.065" Dual Line Replacement String Trimmer Line Spool, 3 count (Pack of 1)

What It Is

This is a pack of three pre-wound 0.065-inch dual-line replacement spools for Greenworks string trimmers. Designed for light to medium trimming of grass and weeds around edges and fences.

Fitment & Compatibility

• Line diameter: 0.065" (1.65mm) – only fits trimmers that accept this thin line. Do not use on heavier-duty trimmers requiring 0.080" or 0.095" line.
• Compatible models: Works with most Greenworks 40V, 60V, and 80V cordless trimmers (e.g., models ST40B00, ST60B00, ST80L00). Also fits select Sun Joe and Kobalt 40V/80V trimmers using the same spool design.
• OEM vs aftermarket: These are genuine Greenworks parts, so fit and performance are guaranteed for compatible models.
• What to check: Look at your current spool – if it has a small center hub and uses 0.065" line, this will work. Measure your existing line diameter with a caliper or ruler to confirm. Check your manual for part number 341024242A or similar.

Key Things to Know

• Installation is tool-free: Snap the spool into the bump head, thread the line through the eyelets, and you’re done. No winding required.
• Line breaks easily on heavy weeds: 0.065" line is thin and cuts grass well but snaps quickly against thick brush or rocks. Use for light-duty trimming only.
• Pre-wound spools save time: You get three spools ready to go – no measuring or winding. Great for quick swaps during a job.
• Common gotcha: Ensure the bump head is fully seated before use. If the spool rattles or won’t feed, check that the line isn’t tangled inside the head.

Should You Buy It

Buy this if you own a compatible Greenworks (or Sun Joe/Kobalt) trimmer and need a hassle-free, genuine replacement for light trimming around lawns and gardens. Avoid it if you trim heavy brush or need thicker line – you’ll burn through these spools fast. For the price, it’s a solid value for casual users who want reliable, no-wind spools.
