Cluparis 5-Pound Heavy Duty Square Trimmer Line .155-inch-by-492-ft Commercial String Trimmer Line in Spool, 0.155" Nylon Weed Eater String with Line Cutter, Red

What It Is

The Cluparis 5-Pound Heavy Duty Square Trimmer Line is a bulk spool of 0.155-inch diameter nylon string designed for commercial-grade gas trimmers and high-use residential mowing. It’s meant for heavy clearing, thick weeds, and edging along fences or walls.

Fitment & Compatibility

Before buying, measure your trimmer’s existing line diameter—0.155 inch is thicker than standard 0.080–0.095 inch lines and may not fit smaller electric or battery trimmers. Check your trimmer’s manual for maximum line diameter and spool capacity; this 5-pound spool works best with bump-feed or fixed-line heads that accept bulk line. It’s aftermarket, not OEM-specific, so it fits most gas trimmers (e.g., Echo, Stihl, Husqvarna, Ryobi) that support 0.155-inch line. Verify your trimmer head has a line cutter (included) or a built-in blade for this square profile.

Key Things to Know

• Quality & durability: The square shape cuts through brush and weeds more aggressively than round line, but it wears faster on abrasive surfaces like concrete or stone.
• Installation difficulty: Moderate—loading 492 feet of line onto a spool takes patience; use a line winder or drill-powered spooler to avoid tangles.
• Common gotchas: The 0.155-inch diameter may jam in trimmer heads designed for thinner lines (0.095–0.130 inch). Also, the included line cutter is basic—replace it if your head has a worn blade.
• Weight: At 5 pounds, this spool is heavy; store it in a dry place to prevent the nylon from absorbing moisture and becoming brittle.

Should You Buy It

Buy this if you run a gas trimmer that accepts 0.155-inch line and need a bulk, long-lasting spool for heavy-duty clearing—it’s a solid value for commercial users or large properties. Skip it for electric trimmers or if you prefer lighter, round line for light trimming.
