KAKO 155 Trimmer Line, 155 Weed Eater String, 155 Weed Trimmer Line, Square String Trimmer Line .155 Inch-285 Ft-3 Lb, Commercial Nylon Trimmer Line .155 Fits Most String Trimmers(Square)

What It Is

The KAKO 155 is a 0.155-inch square trimmer line designed for heavy-duty commercial and residential use, fitting most standard string trimmers. It cuts through thick weeds, brush, and overgrown grass without excessive fraying or frequent reloads.

Fitment & Compatibility

Check your trimmer’s line diameter spec (usually printed on the head or in the manual) – this 0.155-inch line works with most trimmers that accept .155” or .130”–.160” line. It is not compatible with .080”, .095”, or .105” heads. Fits popular brands like Husqvarna, Stihl, Echo, Ryobi, and Craftsman, but avoid use on low-powered electric trimmers (under 4 amps) or string-only heads that require thinner line (e.g., many battery trimmers). Measure your existing line with a caliper if unsure. Not OEM-specific; it’s a durable aftermarket alternative.

Key Things to Know

• Square shape provides sharper cutting edges than round line, reducing engine strain and improving cutting efficiency in thick grass.
• 285 feet per 3-lb spool – enough for multiple reloads; good value for commercial use but heavy for occasional homeowners.
• Installation is straightforward – no special tools needed, but you may need to cut it to length for bump-feed heads. Avoid overloading trimmer heads designed for shorter line (check head capacity).
• Common gotcha: The line is stiff and can be brittle in cold weather; warm it slightly (e.g., in your hands) before loading to prevent snapping.

Should You Buy It

Buy this if you have a mid-to-high-powered gas or corded electric trimmer and need a tough, long-lasting line for heavy brush or frequent commercial use. Skip it if you own a low-voltage battery trimmer, a lightweight electric, or a head that only accepts thinner .080”–.105” line.
