Cluparis .155-Inch Heavy Duty Trimmer Line, 5lb 492ft Professional Square Weed Eater String, 3-Component Tri-Extrusion for Extra Durability, Fits Echo Husqvarna Ryobi, with Super Line Cutter

What It Is

This is a heavy-duty .155-inch square trimmer line designed for commercial-grade use. It’s a 5lb spool (492ft) made with a tri-extrusion process for extra durability, suitable for clearing thick weeds and overgrowth on gas trimmers.

Fitment & Compatibility

Before buying, check your trimmer’s line diameter limit—.155-inch fits most standard gas trimmers (Echo, Husqvarna, Ryobi) but not all electric models (many accept .080–.105-inch). Verify your trimmer head’s maximum line size in the manual. This is aftermarket (not OEM) line; it will work in any bump-feed, fixed-line, or automatic head that accepts .155-inch. No deck size check needed—this is string, not a blade or deck part.

Key Things to Know

• Durability: The tri-extrusion and square shape reduce fraying and improve cutting on thick weeds, but it’s stiffer than round line—expect more noise and vibration.
• Installation: Easy to load if your head accepts .155-inch; use the included Super Line Cutter tool to trim ends quickly. No special tools needed.
• Common gotcha: The 5lb spool is large—may not fit smaller trimmer heads (e.g., some Ryobi 40V models). Check head capacity or plan to reload frequently.
• Value: At ~$0.14/ft, it’s cheaper per foot than most .155-inch line, but the bulk spool is heavy for casual use.

Should You Buy It

Buy it if you run a gas trimmer (Echo, Husqvarna, Ryobi) on heavy-duty tasks like clearing blackberries, brush, or roadside weeds, and you want a durable, long-lasting line without frequent reloads. Skip it if you have a lightweight electric trimmer or only do light grass trimming—the stiff line may cause breakage or head wear.
