Oregon Magnum Gatorline 105 Trimmer Line Heavy Duty, Professional Square Weed Wacker String for Gas and Electric Grass Trimmer and Brushcutters, Fits Most Standard Models .105" x 564-Foot (22-805)

What It Is

The Oregon Magnum Gatorline 105 is a .105-inch diameter, square-profiled trimmer line designed for heavy-duty weed whacking and brushcutting on both gas and electric trimmers. It’s built to handle thick weeds, briars, and light brush where standard round line would snap or wear out quickly.

Fitment & Compatibility

Before buying, confirm your trimmer’s line diameter compatibility. The .105-inch (2.7mm) line fits most standard gas trimmers and larger electric models—check your owner’s manual for the maximum line diameter your head can accept. This spool holds 564 feet, so it’s intended for bulk reloading into reusable spools or cutting to length for fixed-line heads. It works with both bump-feed and manual-feed heads, but not pre-wound spools. If your trimmer uses a proprietary spool (e.g., some EGO or Ryobi models), you’ll need to re-spool manually. Measure your existing line diameter with calipers to be certain.

Key Things to Know

• Durability: The square edges act as blades, cutting through thick growth faster than round line, but they also wear faster on pavement or rocks—expect shorter life if you hit hard surfaces.
• Installation: Rewinding 564 feet onto a spool is tedious. Use a line winder or drill attachment to save time. Cutting line to 10-12 foot lengths for fixed heads is straightforward.
• Noise & Vibration: The square profile can create more noise and vibration than round line, especially on smaller trimmers. Not ideal for light trimming near flower beds.
• Storage: Keep the spool in a dry, cool place. The line can become brittle if exposed to direct sunlight or extreme heat for long periods.

Should You Buy It

Buy this if you have a gas or high-power electric trimmer and regularly tackle heavy weeds, briars, or brush where standard line fails. Skip it if you only trim grass around lawns or need a pre-wound spool for a proprietary head—you’ll waste time and money on overkill.
