Cluparis .155-Inch Heavy Duty Trimmer Line, 1lb 102ft Professional Sawtooth Weed Eater String, 3-Component Tri-Extrusion for Extra Durability, Fits Echo Husqvarna Ryobi, with Super Line Cutter

What It Is

This is a 0.155-inch heavy-duty trimmer line designed for gas-powered string trimmers, featuring a sawtooth edge and tri-extrusion construction for cutting thick weeds and brush. It’s a 1-pound spool (102 feet) intended for residential or commercial use where standard round line fails.

Fitment & Compatibility

• Line diameter: 0.155 inch fits most gas trimmers that accept 0.105–0.155 inch line (check your manual’s max line size). Not for electric or battery trimmers—those typically use 0.065–0.095 inch.
• Brands listed: Echo, Husqvarna, Ryobi gas models. For Ryobi, it fits 40V/18V brushless gas trimmers (e.g., RY43160, RY253SS). Verify your trimmer head accepts bump-feed or fixed-line loading—some require pre-cut strips.
• OEM vs aftermarket: Aftermarket line. Works in most standard heads, but may not fit speed-feed or quick-load heads without trimming to length.
• Measurements: 1 lb spool = 102 ft. Cut to 8–12 inch strips per head instruction. Sawtooth profile may not feed smoothly in all bump heads.

Key Things to Know

• Quality: Tri-extrusion adds durability, but sawtooth edges can wear faster on abrasive surfaces (concrete, rocks). Expect shorter life than round line in clean grass.
• Installation: Easy if your head accepts bulk spool winding—no special tools. For pre-cut heads, you’ll need to cut strips manually. Avoid over-tightening when winding.
• Common gotchas: The sawtooth design can cause more vibration in some heads. Not for lightweight electric trimmers—line may jam or break the head. Check your trimmer’s line diameter limit before buying (0.155 is thick).
• Rating context: 3.7 stars—some users report uneven feeding or rapid wear on rough terrain. Works best for heavy weeds, not daily mowing.

Should You Buy It

Buy if you have a gas trimmer that handles 0.155-inch line and you regularly cut thick brush or overgrown weeds. Skip if you mow mostly grass on clean lawns—a standard round line will last longer and feed more reliably.
