.155" Star Trimmer Line (130 ft / 1 lb Donut Spool) - Industrial Weed Wacker String & Weed Eater Line for Fixed-Head Trimmers ONLY - Heavy Duty 5-Point Brush Cutter Cord - Free Cutter | Premium Co-Polymer Nylon, Prevents Grass Tearing, High Impact

What It Is

This is a heavy-duty, 0.155-inch diameter star-shaped trimmer line on a 1-pound donut spool (130 ft). Designed for fixed-head trimmers only, it’s built for commercial-grade brush cutting and thick weeds, not standard residential grass trimming.

Fitment & Compatibility

• Trimmer head type: Fixed-head (manual or bump-feed) only. Not compatible with Speed-Feed, Tap-N-Go, or automatic-feed heads.
• Line diameter: 0.155" (4.0 mm). Confirm your trimmer’s max line size—most standard heads accept up to 0.130". Check owner’s manual or head markings. Too thick can jam or damage the head.
• Spool type: Donut spool (center hole). Fits most standard fixed-head spools that accept bulk line—no pre-wound spool.
• Brand/model: Universal for fixed-head trimmers (e.g., Echo, Husqvarna, Stihl, Ryobi, Craftsman) but verify head compatibility.
• What to measure: Head opening width and line exit hole diameter. If holes are <0.155", don’t force it.

Key Things to Know

• Star shape cuts better: The 5-point edge reduces grass tearing and gives cleaner cuts vs. round line, but it’s louder and more aggressive.
• Installation is manual: You’ll need to wind the donut spool yourself. No pre-wound spool—use a drill or hand-wind evenly to avoid tangling.
• Free cutter included: A small blade attachment to trim line to length. It’s basic but functional.
• Not for electric trimmers: The heavy line can overload low-power electric motors. Best for gas trimmers 30cc+ or commercial battery units.
• Durability trade-off: Co-polymer nylon resists heat and breakage, but the star profile wears faster on pavement or rocks.

Should You Buy It

Buy this if you have a fixed-head gas trimmer (30cc or larger) and need serious brush-cutting power—thick vines, brambles, or overgrown weeds. Skip it if you have a standard residential trimmer, an automatic-feed head, or mostly trim grass near sidewalks (the star shape will chew up quickly on hard surfaces).
