Cluparis Round String Trimmer Line.105-Inch-by-1129-ft 5-Pound Grass Trimmer Line Donut, Round-Shaped Nylon Weed Eater String, with Line Cutter, Orange

What It Is

This is a 5-pound donut of 0.105-inch-diameter (2.7mm) round nylon trimmer line, designed for gas and electric string trimmers that accept universal spool refills. The included line cutter adds convenience for on-the-go trimming.

Fitment & Compatibility

Before buying, check three things:

• Line diameter: 0.105-inch fits most standard trimmers, but verify your model’s max line size—too large can jam the spool or damage the head.
• Spool type: This is a bulk donut, not a pre-wound spool. It works with any trimmer that lets you hand-wind line onto a reusable spool (common on gas trimmers like Echo, Husqvarna, Stihl, and Ryobi). Not compatible with “bump-feed” heads that require pre-cut lines or specific spool shapes.
• Measurement: Donut outer diameter is about 6 inches; ensure your trimmer head has enough clearance to load the bulk line without interference.

Key Things to Know

• Quality: 100% nylon, round profile. Durable for light-to-medium weeds and grass, but round line wears faster than square or serrated shapes on thick brush.
• Installation: Easy to load—cut a length, thread through the spool, and wind. The included cutter helps, but a sharp knife works too.
• Common gotcha: The donut is tightly wound; unwind slowly to avoid tangles. Store in a dry place to prevent the nylon from becoming brittle.
• Value: 1,129 feet at this price is cost-effective compared to pre-wound spools, but you’ll need to spool your own heads.

Should You Buy It

Buy this if you own a standard gas or electric trimmer that accepts bulk line, you go through string quickly (e.g., frequent trimming on a large property), and you don’t mind manually winding spools. Skip it if you need pre-cut lines for a specific bump-feed head or if you tackle heavy brush—square or serrated line would last longer.
