.105 Inch Round String Trimmer Line, Commercial Weed Eater String with Line Cutter-1126Ft Fits Most String Trimmer

What It Is

This is a 0.105-inch diameter round trimmer line, sold in a 1,126-foot spool, designed for commercial-grade weed eaters. It’s meant for heavy-duty cutting of thick grass and light brush, and includes a built-in line cutter for quick length adjustments.

Fitment & Compatibility

• Line diameter: 0.105 inch – fits most trimmer heads that accept line from 0.080 to 0.110 inch. Check your trimmer’s manual or head for the max line size (using too thick a line can overload the engine or damage the head).
• Spool size: 1,126 feet – not a pre-wound spool; you load it onto your own trimmer head. Works with bump-feed, manual-feed, and fixed-line heads.
• Brand fit: Universal aftermarket line – not OEM-specific. Fits brands like Echo, Stihl, Husqvarna, Ryobi, Troy-Bilt, and Craftsman, provided the head accepts 0.105-inch line.
• What to check before buying: Confirm your trimmer head’s line diameter range (often printed on the head or in the manual). Also verify the head type – some fixed-line heads require a specific line shape (round vs. square), but round works in most.

Key Things to Know

• Quality: Commercial-grade, round cross-section – durable for heavy use but not the best for thick, woody brush (square or star-shaped line is more aggressive).
• Installation: Easy – just cut to length, wind onto your spool, and thread through the eyelets. The included line cutter is a small blade on the spool edge; it’s handy but not sharp enough for thick line.
• Gotchas: The “1126Ft” length is total – you’ll get many refills. But if your trimmer takes pre-wound spools, you’ll need to wind it yourself, which takes a few minutes. Also, round line wears faster than twisted or serrated line in abrasive conditions.

Should You Buy It

Buy this if you have a commercial or heavy-duty string trimmer that takes 0.105-inch line and you go through line quickly (large lawns, rental properties, or frequent trimming). It’s a solid value for the price per foot, but if you tackle dense brush or need a more aggressive cut, consider a square or star-shaped line instead.
