KAKO 065 Trimmer Line, 065 Weed Trimmer Line, Weed Wacker String .065, Square Weed Eater String .065 Inch-1680 Ft- 3 Lb, Commercial Nylon Trimmer String 065 Fits Most String Trimmers(Square)

What It Is

The KAKO 065 Trimmer Line is a .065-inch square commercial-grade nylon string designed for heavy-duty trimming in gas, electric, and battery-powered string trimmers. It’s meant for clearing thick grass, light brush, and overgrown weeds.

Fitment & Compatibility

• Line diameter: .065 inch (1.65 mm) – fits most trimmers that accept this size, including common brands like Echo, Stihl, Husqvarna, Ryobi, and Troy-Bilt. Check your trimmer’s manual or existing line for the exact diameter.
• Shape: Square profile cuts more aggressively than round line but may not spool well in trimmers with narrow or fixed-line holes. Ensure your trimmer’s cutting head accepts square line (most bump-feed and fixed-head models do).
• Length: 1,680 ft on a 3-lb spool – enough for many seasons of heavy use. Not pre-cut; you’ll need to cut your own lengths.
• Aftermarket: Works as a direct replacement for OEM .065 line. No adapter needed.

Key Things to Know

• Durability: Commercial-grade nylon resists melting and fraying better than cheaper round line, especially on asphalt or concrete edges.
• Installation: Easy to load into standard bump-feed or fixed heads – just cut to length and wind. Square line may be slightly stiffer than round, so take care not to overlap tightly.
• Noise & wear: Square edges produce more noise and vibration than round line, and can wear out trimmer head guides faster over time.
• Not for very small trimmers: Some lightweight electric trimmers (e.g., Black+Decker 20V) may struggle with .065 square line due to motor load or head fit.

Should You Buy It

Buy it if you have a mid-to-large gas trimmer or a high-power electric model and need durable line for heavy trimming on rough terrain or edges. Skip it if you use a small electric trimmer or prefer low-noise, low-vibration round line for light yard work.
