Oregon Magnum Gatorline Square Trimmer Line .105 in – 1 lb Donut

Overview

The Oregon Magnum Gatorline Square trimmer line is built for professionals and serious backyard crews who need reliable, long‑lasting performance. With a .105 inch gauge, this line sits well between lighter and heavier options, offering strength without excessive wear. Packaged on a convenient 1‑pound donut, it’s ready for quick refills and uninterrupted work sessions.

Designed to deliver steady, powerful cuts, this line blends toughness with precision. Its square profile helps create clean passes, while the outer layer is engineered to resist weld‑through and line bonding in the trimmer head.
