What It Is

This is a 0.105-inch (2.7mm) square trimmer line designed for commercial-grade string trimmers and heavy-duty residential use. It’s a bulk spool (1 lb, 203 ft) meant to replace worn line on any trimmer head that accepts 0.105” diameter line—great for thick weeds, tall grass, and edging.

Fitment & Compatibility

Before buying, check these three things:

• Trimmer head diameter limit – Most trimmer heads are marked with a max line size (e.g., 0.095”, 0.105”, 0.130”). This line is 0.105”, so it fits heads rated for 0.105” or larger. If your head only takes 0.080” or 0.095”, it will not fit.
• Trimmer brand/model – Works with any brand (Honda, Stihl, Echo, Ryobi, etc.) as long as the head accepts 0.105” line. No proprietary lock-in.
• OEM vs aftermarket – This is a universal aftermarket line. It will work fine in OEM heads, but check your head’s loading method (bump-feed, fixed, or slide-through). Square profile cuts better than round but may be slightly stiffer to load.

Pro tip: Measure your current line diameter with a caliper or match the number on your existing line spool. If you’re unsure, 0.105” is common for mid-size commercial trimmers.

Key Things to Know

• Soak before use – The manufacturer explicitly says to soak the line in water for 24 hours before spooling. This softens it slightly, reduces breakage, and improves feeding. Skip this and you’ll get more snapping.
• Square vs round – Square edges cut grass and weeds faster and quieter than round line, but they wear down to a round shape over time. Expect shorter lifespan per cut than thicker line.
• Installation difficulty – Moderate. Stiffer than typical 0.080” line, so winding a full spool requires some hand strength. Use a line winder tool if you have one.
• Common gotcha – This line is 0.105”, not 0.095” or 0.130”. Double-check your head’s max spec. Also, it’s 203 ft total—enough for several reloads on most trimmers.

Should You Buy It

Buy this if you have a mid-size commercial or heavy-duty residential trimmer that takes 0.105” line and you want a durable, square-profile line that cuts through thick weeds without constant breakage. It’s a solid value for the price, especially if you don’t mind the 24-hour soak. Skip it if your head only accepts smaller line or you prefer pre-wound spools for convenience.
