.105" Pentagon String Trimmer Line 1LB Weed Eater String Orange Fit for Grass Trimmers & Edgers

What It Is

This is a 0.105-inch (2.7mm) diameter Pentagon-shaped trimmer line, sold in a 1-pound spool. It’s designed for gas, electric, and battery-powered string trimmers and edgers that accept this line size—ideal for light to medium-duty trimming of grass and light weeds around lawns, gardens, and walkways.

Fitment & Compatibility

Before buying, check your trimmer’s line diameter requirement—most will list a range (e.g., .080”–.105”). This .105” line is thicker than standard .080” or .095” lines, so it may not fit trimmer heads designed for smaller diameters unless the head can accept it. It’s not brand-specific; you can use it in any trimmer head that fits .105” line, including Weed Eater, Echo, Husqvarna, Ryobi, and others. No OEM part needed—this is aftermarket. Also check your trimmer head’s loading method: bump-feed, fixed-line, or manual-load. Pentagon shape fits all standard heads but may be slightly stiffer than round line, so ensure your head can handle a firm line without jamming.

Key Things to Know

• Quality: Pentagon shape cuts more aggressively than round line, reducing the need for multiple passes on light weeds. The 1lb spool is generous—expect 50–70 feet of line.
• Installation: Easy to load on most trimmer heads—just cut a length (usually 10–15 feet), thread, and wind. No special tools needed. Check your manual for maximum line length per side.
• Gotcha: This line is thicker and stiffer than standard. On smaller or older trimmer heads with tight tolerances, it may not feed smoothly or could break during bump-feed. Test a short length first.
• Common issue: The orange color fades quickly in sunlight, but performance is unaffected. Some users report the line wears faster than premium brands like Oregon or Echo on heavy-duty use.

Should You Buy It

Buy this if you have a trimmer that accepts .105” line and you want a budget-friendly upgrade from round line for faster trimming of grass and light weeds. It’s not for heavy brush or commercial use—stick with thicker, more durable line for that. Good value for occasional homeowners.
