A ANLEOLIFE 1-Pound Commercial Square .065-Inch-by-370-ft String Trimmer Line Donut,with Built-in Line Cutter, Orange

What It Is

This is a 1-pound donut of .065-inch commercial-grade square trimmer line, 370 feet long, with a built-in line cutter integrated into the spool. It’s designed for heavy-duty trimming on gas, electric, and battery-powered string trimmers with bump-feed or fixed-line heads.

Fitment & Compatibility

Before buying, check your trimmer’s line diameter spec – .065-inch is common for mid-sized trimmers (e.g., Echo SRM series, Stihl FS 55/56, Husqvarna 128LD). Measure your head’s spool width; this donut fits most standard 1-pound spools but may not work with smaller heads (e.g., Ryobi 40V or DeWalt 20V trimmer heads with narrow spool slots). It’s aftermarket, not OEM, so verify your head accepts universal donuts. If your trimmer uses pre-cut lines or .080-inch or .095-inch line, skip this.

Key Things to Know

• Square shape cuts better: The square profile slices through thick weeds and grass faster than round line, with less noise and vibration.
• Built-in cutter is handy: The integrated cutter on the spool lets you snap off line without a separate tool, but it’s plastic and may wear out over time.
• Installation is straightforward: Load the donut into your spool as you would any pre-wound line – no winding required. Check your manual for the correct line exit direction (clockwise vs. counterclockwise).
• Common gotcha: If your trimmer head has a small line exit hole, the .065-inch line can slip out easily if not fed correctly. Use a lighter to melt the tip slightly to prevent fraying.

Should You Buy It

Buy this if you have a mid-size gas or electric trimmer that uses .065-inch line and want a commercial-grade option with a built-in cutter for quick reloads. It’s a solid value for heavy trimming but skip it if your head requires thicker line or a specific OEM donut.
