Cluparis .105-Inch Heavy Duty Trimmer Line, 5lb 1129ft Professional Sawtooth Weed Eater String, 3-Component Tri-Extrusion for Extra Durability, Fits Echo Husqvarna Ryobi, with Super Line Cutter

What It Is

The Cluparis .105-Inch Heavy Duty Trimmer Line is a 5lb spool (1,129 feet) of professional-grade sawtooth string designed for gas and electric string trimmers. It uses a 3-component tri-extrusion process for extra durability and includes a built-in line cutter on the spool.

Fitment & Compatibility

Before buying, verify your trimmer accepts .105-inch (2.7mm) diameter line—this is a medium-heavy gauge, common in Echo, Husqvarna, and Ryobi trimmers with a bump-feed or fixed-line head. Not all trimmer heads can handle .105; check your owner’s manual for max line diameter. This is an aftermarket spool, not OEM, so it may require slight trimming to fit some bump-feed heads. The spool is pre-wound and ready to use, but you must confirm your trimmer uses a universal spool (most Echo and Ryobi do; some Husqvarna models use a dedicated spool). Measure your existing spool’s width and center hole diameter to ensure compatibility.

Key Things to Know

• Quality vs price: At $66.99, this is premium line. The sawtooth profile cuts through thick weeds faster than round line, but the tri-extrusion can feel stiff and may break more easily on rocks or concrete edges.
• Installation: The pre-wound spool is easy to install if it fits your head. If it doesn’t, you can re-spool the line onto your existing spool—but that adds time and wastes some line.
• Common gotchas: The 5lb spool is heavy; it’s best for commercial use or large properties. For home use, a smaller spool is more practical. The built-in cutter works well but can dull over time.
• Noise/vibration: Some users report the sawtooth design creates more vibration and noise than standard round line.

Should You Buy It

Buy this if you have a high-volume trimming job (large yard, commercial use) and your trimmer accepts .105 line. It’s a durable, fast-cutting option for thick grass and brush, but the high price and stiff line make it overkill for occasional home use. For light-duty trimming, a cheaper .095 or .080 line will work fine.
