Weed Eater String, 065 String Trimmer Line of 580-Feet, Heavy Duty Weed Wacker String for Universal Replacement, Round Weed Trimmer Line Fits Medium&Heavy Grass&Weed, Weedeater Line of Premium Nylon

What It Is

This is a 580-foot spool of 0.065-inch diameter round nylon trimmer line, designed for heavy-duty use in medium to heavy grass and weeds. It’s a universal replacement line that fits most gas, electric, and battery-powered weed eaters using a 0.065-inch line.

Fitment & Compatibility

Before buying, confirm your trimmer’s line diameter requirement (check the manual or existing line spool). This 0.065-inch line is a common medium gauge, fitting most residential trimmers from brands like Weed Eater, Troy-Bilt, Ryobi, Husqvarna, and Echo, as well as many off-brands. It will not fit trimmers that require larger diameters (0.080–0.095 inch) or smaller (0.050 inch). The line is round, so it’s compatible with bump-feed, fixed-head, and automatic-feed spools. No need to buy a specific OEM brand—this is an aftermarket replacement. Measure your existing line diameter with a caliper if unsure; 0.065 inch is about 1.6 mm.

Key Things to Know

• Quality: Made of premium nylon, so it’s more durable than budget lines and less prone to snapping on thick weeds. It resists melting and stretching better than standard trimmer line.
• Installation: Easy to load into most spools—just cut to length and wind. The 580-foot spool gives you many refills (typically 10–20+ depending on your trimmer’s spool capacity).
• Common gotchas: Round line works well for grass and light weeds but may struggle with very thick, woody brush (use a star or twisted line for that). Also, 0.065-inch is on the thinner side for heavy-duty jobs—if your trimmer can handle 0.080-inch, consider that for tougher vegetation.
• Storage: Keep the spool in a dry place to prevent the nylon from becoming brittle over time.

Should You Buy It

Buy this if you need a cost-effective, universal 0.065-inch trimmer line for regular lawn maintenance with medium to heavy grass and weeds. It’s a solid value at $12.99 for 580 feet, and the 4.5-star rating reflects reliable performance. Skip it if your trimmer requires a larger diameter or if you primarily cut thick brush—look for a heavier-gauge or shaped line instead.
