Trimmer line .105" Heavy Duty Weed Eater String .105-Inch String Trimmer Line for Most Weed Trimmer Grass Cordless Weed Wacker String -0.105"

What It Is

This is a 0.105-inch diameter trimmer line, a heavy-duty replacement string for gas, cordless, and electric weed trimmers. It’s designed for clearing thick grass, weeds, and light brush where standard 0.080-0.095 inch lines snap too easily.

Fitment & Compatibility

• Line diameter: 0.105 inches (2.67 mm). Only fits trimmers that accept 0.105-inch or larger line (e.g., 0.105, 0.110, 0.130). Do not force it into a trimmer rated for 0.065-0.095 inch—it will jam or damage the spool.
• Spool type: Works with pre-wound spools, bulk refill, and most fixed-line or bump-feed heads. Check if your trimmer uses a specific spool shape (e.g., dual-line or single-line) or has a “twist” loading mechanism.
• Brand/model: No universal fit list. Measure your current line diameter with calipers. Common compatible brands: Echo, Stihl, Husqvarna, Ryobi, Craftsman, Black+Decker—but only if their head supports 0.105 inch.
• OEM vs aftermarket: Aftermarket line. Performance is similar to OEM heavy-duty lines, but may be slightly stiffer. Confirm your trimmer’s manual lists 0.105 inch as acceptable.

Key Things to Know

• Cutting performance: Cuts faster than standard line but wears faster on rough surfaces (concrete, rocks) due to its larger surface area.
• Installation: Moderate difficulty. The thicker line is harder to bend and thread into small spool slots. Soak in warm water for 5 minutes to soften before loading.
• Common gotcha: If your trimmer has a “tap” feed head, this line may not advance smoothly because it’s stiffer. Test with a single strand first.
• Storage: Keep dry and away from sunlight. UV exposure makes the line brittle and prone to snapping.

Should You Buy It

Yes, if you regularly battle dense weeds or overgrowth and your trimmer supports 0.105-inch line. It’s a good value for heavy-duty use, but skip it if you only trim light grass or have a small electric trimmer that recommends thinner line—it’ll overwork the motor and reduce runtime.
