Oregon 22-580 Magnum Gatorline Round Trimmer Line .080-Inch Diameter, 5 Pounds

What It Is

The Oregon 22-580 Magnum Gatorline is a heavy-duty .080-inch diameter round trimmer line, sold in a 5-pound spool. It’s designed for gas and high-end electric string trimmers used in commercial or heavy residential clearing, brush, and tall weeds.

Fitment & Compatibility

Before buying, confirm your trimmer’s line diameter spec—this is .080 inch, not the more common .095 or .105. Check your owner’s manual or the trimmer head for the maximum line diameter allowed; using too thick a line can jam the head or overload the motor. This line fits most bump-feed, auto-feed, and fixed-head trimmers that accept round .080 line, including many EGO, Stihl, Husqvarna, Echo, and Ryobi models. It is not OEM-specific; it’s an aftermarket upgrade. Measure your existing line with a caliper to be sure—eyeballing it often leads to wrong fit.

Key Things to Know

• Quality: This is a premium line with a twisted, multi-sided profile (despite being called “round”) for quieter operation and less vibration than standard round line. It cuts through thick weeds and light brush without breaking often.
• Installation: Easy—manual or power wind. The 5-pound spool is large, so you’ll need to wind your own trimmer spool or use a bulk winder. No special tools required.
• Gotcha: At 5 pounds, this spool is heavy (about the size of a small paint can). It’s not portable for on-the-go reloading—you’ll want to keep it in your garage or shop and wind smaller amounts into your trimmer head.
• Durability: The line is stiff and holds up well on pavement and fences, but it’s not as flexible as softer line, so it may not work well in trimmer heads that require high flexibility for auto-feed.

Should You Buy It

Buy this if you have a .080-inch capable trimmer and do heavy clearing, roadside mowing, or commercial work where you go through line fast. It’s overkill for a small residential lawn with light grass—a smaller spool of .080 line will be cheaper and easier to handle. For heavy users, the 5-pound bulk saves money per foot and reduces trips to the store.
