Arnold .065-Inch x 220-Foot Residential Grade String Trimmer Line

What It Is

This is a .065-inch diameter, 220-foot spool of residential-grade nylon trimmer line for gas, electric, and battery-powered string trimmers. It’s designed for light-duty trimming of grass and small weeds, not heavy brush or thick overgrowth.

Fitment & Compatibility

• Line diameter: .065-inch is standard for most residential trimmers (e.g., Echo, Ryobi, Craftsman, Troy-Bilt, Husqvarna). Do not use on trimmers that require .080-inch or .095-inch line—it will break or feed poorly.
• Spool type: This is bulk line, not pre-wound spools. You’ll need to cut and load it into your existing spool head. Works with bump-feed, fixed-line, and speed-feed heads.
• OEM vs aftermarket: Arnold is a universal replacement brand. It fits most trimmers but check your owner’s manual for recommended line diameter. For DeWalt or Milwaukee 60V trimmers, verify the head accepts .065-inch; some require .080-inch.
• Measurement check: Measure your current line diameter with a caliper or match the number printed on your spool. If it says .065-inch, this works.

Key Things to Know

• Quality: Residential grade—good value for light use. Not as durable as premium line (e.g., Oregon Vortex or Echo Diamond Tip). Expect more frequent refills if trimming near fences or rocks.
• Installation: Easy to load into most heads. No special tools needed. Cut 10-12 feet per trimmer head (depending on head size). The 220-foot spool refills about 18-22 heads.
• Common gotcha: Line can become brittle in cold weather (below 40°F). Store indoors. Also, avoid using on trimmers with automatic line feed systems unless the manual approves .065-inch—thicker line can jam.
• Breakage: Expect more breakage than thicker lines. Not for heavy-duty edging or sidewalk trimming.

Should You Buy It

Yes, if you have a standard residential trimmer (gas or electric) and mostly cut grass and light weeds. It’s a solid, low-cost bulk line for frequent refills. Skip it if you need heavy-duty trimming (thick brush, gravel edges) or if your trimmer requires .080-inch or larger line.
