Oregon 20-106 Platinum Gatorline Supertwist Trimmer Line, .105-Inch, 1/2 Pound

What It Is

The Oregon 20-106 Platinum Gatorline Supertwist Trimmer Line is a .105-inch diameter, 1/2-pound spool of aftermarket trimmer line designed for gas and electric string trimmers, including EGO models. It’s built for medium-to-heavy duty trimming of grass, weeds, and light brush.

Fitment & Compatibility

Before buying, verify your trimmer’s line diameter requirement (check the manual or the head for a stamp). This .105-inch line fits most trimmers that accept .095 to .110-inch line, including EGO Power+ models (e.g., ST1500, ST1511T) and many other brands (Husqvarna, Stihl, Ryobi). It does not fit trimmers that require smaller line (e.g., .080 or .065). This is an aftermarket part—no OEM compatibility issues, but confirm your trimmer head can handle the larger diameter and that the spool fits if using a pre-wound replacement (measure spool width). For bump-feed heads, this line works well; for fixed-line heads, you’ll need to cut and load manually.

Key Things to Know

• Quality: The “Platinum” coating and Supertwist shape reduce wear and breakage compared to round line—lasts noticeably longer in abrasive trimming (sidewalks, fences).
• Installation: Easy to load in bump-feed heads, but the twisted profile can be slightly stiffer to push through the eyelet. Cut at an angle for smoother feeding.
• Gotchas: This line is heavier than standard .095; it may cause some electric trimmers to bog down in thick grass. Check your trimmer’s power rating (e.g., 56V EGO models handle it fine). Not for lightweight electric trimmers under 18V.
• Value: 1/2 pound is enough for several refills (typically 4-6 full loads on a standard head). Price per pound is higher than bulk line, but the performance justifies it.

Should You Buy It

Buy this if you have a medium-to-powerful trimmer (gas or high-voltage electric) and frequently trim against hard surfaces or thick weeds. It’s a durable upgrade over standard round line, especially for EGO 56V users. Skip it if your trimmer requires a smaller diameter line or if you only do light grass trimming—cheaper round line will suffice.
