CRAFTSMAN String Trimmer Line, 0.08-Inch, 3-Pack, 20-feet, Twist line (CMZST0803)

What It Is

This is a pack of three 20-foot spools of 0.08-inch diameter twist-layered string trimmer line, designed for light-duty trimming on electric, battery, or small gas trimmers. The twisted profile reduces noise and improves cutting efficiency on grass and light weeds.

Fitment & Compatibility

Check that your trimmer head accepts 0.08-inch line (common for electric and battery models, but too thin for most gas trimmers that require 0.095–0.105 inch). This is an OEM Craftsman part (CMZST0803), but it fits any trimmer that uses 0.08-inch line—verify your owner’s manual or current line diameter. Does not fit trimmer heads with fixed blade or pre-cut line systems (e.g., SpeedFeed, TapAdvance) unless they accept spool loading. Measure the spool width (standard 2-inch) to ensure it fits your head.

Key Things to Know

• Thin line = light duty only. This line snaps easily against thick weeds, brush, or edging—ideal for weekly lawn touch-ups, not heavy clearing.
• Twist design reduces noise, but you’ll replace line more often than with a thicker round or square line.
• Installation is straightforward on bump-feed heads: wind the line evenly, avoid overlapping, and load per your trimmer’s instructions. No special tools needed.
• 3-pack value means you get 60 feet total, but each spool is only 20 feet—enough for 1–2 full trims on a small yard.

Should You Buy It

Buy this if you own a lightweight electric or battery trimmer (like a Craftsman, Black+Decker, or Ryobi) and only need to maintain a small, well-kept lawn with grass and thin weeds. Skip it for heavy-duty gas trimmers or thick brush—you’ll burn through line too fast.
