Cluparis .155" x 308' String Trimmer Line, 3-Pound Round Weed Eater String Donut, Break-Resistant Nylon Grass Trimmer Cord (Orange, with Line Cutter)

What It Is

This is a 3-pound donut spool of 0.155-inch diameter, 308-foot long round nylon trimmer line, designed for gas, electric, and battery-powered string trimmers. It includes a built-in line cutter for on-the-go trimming, and the bright orange color aids visibility.

Fitment & Compatibility

Before buying, verify your trimmer head accepts 0.155-inch diameter line—common for mid- to heavy-duty trimmers (e.g., Echo, Stihl, Husqvarna, Ryobi, Craftsman). Check your owner’s manual or current line spool for the exact diameter. This is a bulk donut, not a pre-wound spool, so it fits any trimmer head that uses replaceable line (bump-feed, fixed-head, or auto-feed). Measure your trimmer’s line capacity: 308 feet is generous, but if your head holds less than 20 feet per load, you’ll have plenty of refills. OEM compatibility is not required—this is universal aftermarket line.

Key Things to Know

• Break resistance: The nylon is reinforced for durability against fences, rocks, and sidewalks, but avoid heavy brush or thick vines—round line is best for grass and light weeds.
• Installation: Easy to load into any trimmer head; the line cutter on the donut lets you cut to length without scissors. No special tools needed.
• Gotcha: 0.155-inch line is thicker than standard 0.080–0.095-inch line, so it may not fit small electric or battery trimmers with narrow line slots. Always double-check your trimmer’s max line diameter.
• Value: At 308 feet, this spool lasts many refills—cost per foot is lower than buying multiple small spools.

Should You Buy It

Buy this if you have a mid-to-heavy-duty gas or electric trimmer that accepts 0.155-inch line and you want a durable, break-resistant round line for regular lawn maintenance. It’s a solid value for frequent trimming, but skip it if your trimmer requires a smaller diameter (e.g., 0.080 or 0.095 inch) or if you need serrated/star-shaped line for heavy weeds.
