Greenworks 0.065" 240-Foot String Trimmer Line

What It Is

This is a 0.065-inch diameter, 240-foot spool of round trimmer line designed for electric string trimmers, including Greenworks models. It’s meant for light-duty trimming of grass and small weeds, not heavy brush or thick overgrowth.

Fitment & Compatibility

Before buying, check three things:

1. Line diameter: Your trimmer’s manual will specify a max line diameter—usually 0.065” or 0.080”. Using 0.065” in a trimmer rated for 0.080” works, but the reverse (0.080” in a 0.065” rated head) won’t fit or may damage the head.
2. Spool size: This 240-foot spool is large. If your trimmer uses pre-wound spools (not bulk line), you’ll need to manually wind it. Confirm your trimmer accepts bulk line (most Greenworks electric trimmers do).
3. Brand fit: This is OEM Greenworks line, but it’s universal 0.065” round line. It fits any trimmer that accepts 0.065” line—Greenworks, Ryobi, Black+Decker, etc. No proprietary connection needed.

Key Things to Know

• Quality: Standard round line—adequate for grass, but snaps more easily than twisted or star-shaped line on thicker weeds. Expect frequent reloading if you hit tough growth.
• Installation: Easy if you’ve wound a trimmer spool before. Cut a 20–30 foot length, feed through the eyelet, and wind evenly. The 240-foot roll gives you 8–12 refills.
• Common gotcha: This line is 0.065” (1.65 mm), not 0.080” (2.0 mm). If your trimmer is rated for 0.080”, you’ll get less cutting power and faster wear. Check your manual.
• Storage: The spool is not resealable—keep it dry to prevent the line from becoming brittle.

Should You Buy It

Buy this if you have a light-duty electric trimmer (under 12 amps or 40V) and only cut grass or small weeds. It’s a solid value for the price per foot, but skip it if you need thicker line for heavy brush or if your trimmer requires pre-wound spools. For $12, it’s a reliable refill for occasional use.
