Oregon 0.080 in. Gatorline Round Weed Wacker/String Trimmer Line, 1 lb. (416 ft.) Bulk Donut, Fits Stihl, DeWalt, Ryobi and Greenworks 21-380B

What It Is

This is a 0.080-inch diameter round trimmer line in a 1-pound bulk donut (416 feet total), designed for light-to-medium residential trimming on gas, electric, and battery string trimmers. It’s an aftermarket replacement for brands like Stihl, DeWalt, Ryobi, and Greenworks, but listed under EGO for compatibility.

Fitment & Compatibility

• Line diameter: 0.080 in. fits most standard residential trimmers (check your manual for max line size—some heavy-duty models require 0.095–0.105 in.).
• Line shape: Round, so it works with any trimmer head that accepts round line (bump-feed, fixed, or auto-feed). Not for serrated or star-shaped heads.
• Brand compatibility: Fits Stihl, DeWalt, Ryobi, Greenworks, and EGO models that accept 0.080 in. line. Does NOT fit all trimmers—verify your shaft type and head design.
• Measurement check: Measure your current line diameter with calipers or match the number on the package. Using too thick a line can jam the head or overload the motor.
• OEM vs aftermarket: This is an Oregon aftermarket line, not a brand-specific OEM part. It’s a direct replacement for most standard heads, but some proprietary heads (e.g., Stihl AutoCut) may require specific lengths or shapes.

Key Things to Know

• Durability: Oregon Gatorline is a twisted round line that’s more resistant to breaking than basic round line, but it’s still less durable than square or serrated lines for heavy weeds.
• Installation: Easy—spool or cut to length as needed. The bulk donut lets you load multiple spools or heads; just wind evenly to avoid tangles.
• Common gotcha: If your trimmer head has a specific line shape requirement (e.g., star, multi-sided), this round line may not feed properly or may slip.
• Length: 416 ft. is generous—enough for several seasons of light trimming. Store in a dry place to prevent brittleness.

Should You Buy It

Buy this if you need a reliable, affordable 0.080 in. round line for standard residential trimming on most major brands (including EGO) and don’t require heavy-duty weed whacking. It’s a solid value for light grass and edging, but skip it if you need thicker or shaped line for dense brush or commercial use.
