KAKO 105 Trimmer Line, Weed Eater String .105, Weed Wacker String .105, Square String Trimmer Line .105 Inch-1038 Ft-5 Lb, Commercial Nylon Trimmer String.105 Fits Most String Trimmers(Square)

What It Is

This is a 0.105-inch square trimmer line designed for heavy-duty commercial or residential use. It fits most gas and electric string trimmers that accept a .105-inch diameter line, making it suitable for clearing thick weeds, light brush, and overgrown grass.

Fitment & Compatibility

Before buying, verify your trimmer’s line diameter requirement—most models list this in the manual or on the spool cap. The .105-inch square profile works with bump-feed, fixed-head, and reloadable spools, but it may not fit pre-wound spools designed for smaller diameters (e.g., .080 or .095). Check that your trimmer’s cutting head can accommodate a 5-lb bulk spool; some consumer models have limited spool capacity. This is an aftermarket line, not OEM-specific, so it’s compatible with brands like Echo, Husqvarna, Stihl, Ryobi, and others that use .105 line.

Key Things to Know

• Quality & Durability: The square shape provides sharper edges for cutting through tough vegetation, but it may wear faster than round line on abrasive surfaces like concrete or gravel.
• Installation: Reloading a bulk spool takes more time than using pre-wound spools—you’ll need to cut and wind the line yourself. Follow your trimmer’s manual for proper winding direction to avoid jamming.
• Common Gotcha: At 1,038 feet per 5-lb spool, this is a large quantity. Store it in a cool, dry place to prevent the nylon from becoming brittle or sticky over time.
• Noise & Vibration: The square profile can create more noise and vibration than round line, especially at high RPMs—consider ear protection if you’re sensitive to it.

Should You Buy It

If you need a long-lasting, commercial-grade line for heavy trimming on a .105-compatible trimmer and don’t mind winding your own spools, this is a solid value. It’s best for users who go through line quickly (e.g., landscapers or large-lot homeowners) and want a bulk option that cuts aggressively without breaking the bank.
