105 Trimmer Line, 105 String Trimmer Line, 105 Weed Eater String, 3Lbs-0.105Inch-628Ft 105 Weed Wacker String, Commercial Square .105 Trimmer Line, Weed Eater String .105 Fits Most of String Trimmers

What It Is

This is a 0.105-inch diameter, square-shaped commercial-grade trimmer line—3 lbs spool provides 628 feet. Designed for heavy-duty trimming on gas string trimmers, not for light electric or battery models.

Fitment & Compatibility

Must check before buying:

• Line diameter: 0.105 inch works only with trimmers that accept .095–.105 line. Check your manual or the trimmer head’s max line size (often printed on the head).
• Trimmer type: Best for gas trimmers with 30cc+ engines. Too thick for most electric/battery trimmers (typically .065–.080).
• Trimmer head: Works with bump-feed, fixed-line, and quick-load heads—but not with pre-wound spools or heads requiring a specific brand’s proprietary line shape.
• OEM vs aftermarket: No brand specified; fits any trimmer that accepts .105 line. No adapter or special spool needed.

Key Things to Know

• Cutting power: Square profile cuts through thick weeds, briars, and light brush better than round line. Less whipping and breakage on fences or rocks.
• Installation: Manual winding required—no pre-wound spool. Measure line length (typically 15–20 ft per side) to avoid overfilling the head.
• Spool size: 3 lbs is a bulk spool. If you only trim a small lawn, you’ll have leftover line for years. Better for commercial use or large properties.
• Noise/feedback: Thicker line creates more vibration and noise on smaller trimmers. May cause engine bogging on underpowered units.

Should You Buy It

Buy this if you have a gas trimmer with a 30cc+ engine, trim heavy weeds or brush regularly, and want a durable, long-lasting line that won’t snap on contact. Skip it if you use a battery or electric trimmer, or if you only edge a small lawn—you’ll waste money and line.
