UCINNOVATE 105 Weed Eater String Trimmer Line, 216ft/66m Round Weed Eater String Heavy Duty, Commercial Grade Premium Nylon Trimmer Line for Universal Replacement (Orange)

What It Is

This is a 216-foot spool of 0.105-inch diameter round nylon trimmer line, designed for heavy-duty commercial use on gas, electric, and battery-powered string trimmers. It’s for clearing thick grass, weeds, and light brush where standard 0.080 or 0.095 line snaps too easily.

Fitment & Compatibility

• Diameter: 0.105 inches (2.67mm). Fits most trimmers that accept line this thick—check your owner’s manual for the max diameter. Many consumer trimmers max out at 0.095 or 0.100; using 0.105 may overload the head or damage the engine.
• Length: 216 feet. Universal spool size fits standard trimmer heads (bump-feed, fixed-line, or pre-wound spools). Does not fit speed-feed or specialty heads that require pre-cut pieces.
• Brand Fit: No OEM restriction. Works with any brand (Husqvarna, Echo, Stihl, Ryobi, etc.) as long as the diameter is compatible.
• What to Check: Measure your current line diameter. If your trimmer’s manual says “max 0.095,” do not use this line. Also confirm your head can hold a full 216ft spool (some compact heads need shorter lengths).

Key Things to Know

• Durability: Commercial-grade nylon resists fraying and snapping better than standard line, but it’s stiff—may be harder to feed in bump heads initially.
• Installation: Simple. Unspool, wind evenly onto the trimmer head (follow your head’s direction arrows). No tools needed.
• Common Gotcha: If your trimmer is under 25cc or battery-powered, the thicker line can bog down the motor or drain battery faster. Stick to 0.095 or smaller for light trimmers.
• Performance: Round profile cuts cleanly but is less aggressive than star or square line for heavy brush. Best balance for general tall grass and weeds.

Should You Buy It

Buy this if you have a mid-size to large gas trimmer (25cc+) or a high-torque electric model and need a durable, long-lasting line for frequent heavy-duty trimming. Skip it if your trimmer is a small electric or battery unit under 20cc, or if you prefer a multi-sided line for maximum cutting aggression.
