Oregon 69-191B Magnum Gatorline Square Trimmer line, 0.105 in by 50 ft

Oregon Magnum Gatorline® Square Trimmer Line, .105" x 50' Donut – Part #69-191B

Get professional-grade cutting performance in a convenient refill size with Oregon Magnum Gatorline® Square Trimmer Line. Designed for maximum durability and cleaner, more aggressive cutting, Magnum Gatorline® features an advanced co-extruded dual-layer construction that combines a high-strength inner core with a thick, wear-resistant outer layer. This premium design absorbs impacts, minimizes line breakage, and stands up to repeated contact with fences, trees, curbs, landscaping, and other hard obstacles where standard trimmer line quickly wears down.

The square profile features four sharp cutting edges that slice through thick grass and stubborn weeds with clean, efficient cuts. Compared to traditional round trimmer line, the square design contains 27% more material, providing increased durability, longer service life, and superior cutting performance in demanding conditions.

The .105" diameter is ideal for trimming thick grass, heavier weeds, and routine light commercial landscaping. Packaged in a compact 50-foot donut, this refill is perfect for quick spool replacements, seasonal maintenance, or keeping a spare on hand. The donut-style packaging helps reduce tangles and keeps the trimmer line neatly organized.

Compatible with most fixed-line, semi-automatic, and bump-feed trimmer heads, Oregon Magnum Gatorline® works with most gas, battery-powered, and electric string trimmers designed to accept .105" trimmer line.
