Arnold Trimline .080-Inch x 140-Foot Residential Grade Trimmer Line

What It Is

The Arnold Trimline .080-Inch x 140-Foot Residential Grade Trimmer Line is a round, single-strand nylon trimmer line designed for light-to-moderate residential yard work, such as edging lawns and trimming grass around flower beds or fences.

Fitment & Compatibility

• Line diameter: .080 inches (2.0 mm) – fits most standard gas, electric, and battery-powered string trimmers that accept .080 or .065-.095 line. Check your trimmer’s manual or spool cap for the maximum line diameter; using a line that’s too thick can damage the spool or motor.
• Length: 140 feet – enough for multiple refills (typically 4-6 spool loads, depending on trimmer head design).
• Brand/model fit: Universal – works with most trimmer brands (e.g., Ryobi, Echo, Husqvarna, Black+Decker, Toro, Craftsman). Not for use with bump-feed or automatic-feed heads that require pre-cut line lengths or specific line shapes (e.g., twisted, serrated). No OEM-specific compatibility issues.
• Before buying: Confirm your trimmer’s line diameter tolerance (often printed on the spool or in the manual). If your trimmer requires .065 or .095 line, this .080 line may feed poorly or break prematurely. Also check if your trimmer head uses pre-cut lengths or continuous spool refill—this is a continuous spool.

Key Things to Know

• Quality: Residential grade – less durable than commercial/professional line. Expect faster wear on thick weeds, gravel, or concrete edges. Best for grass and light brush.
• Installation: Easy – no tools required. Simply wind the line onto the spool in the direction indicated by the arrows. Common mistake: winding too tightly or in the wrong direction, causing feeding issues.
• Gotcha: Round line is less effective at cutting tough or fibrous weeds compared to square or serrated line. If your yard has heavy weeds, consider upgrading to a twisted or star-shaped line.
• Cost per foot: ~$0.06/ft – very economical for basic trimming.

Should You Buy It

Buy this if you have a standard residential trimmer, maintain a small-to-medium lawn with grass and light weeds, and want a reliable, low-cost line for routine trimming. Avoid it if you frequently tackle thick brush, heavy weeds, or abrasive surfaces—you’ll need a heavier-duty (e.g., .095 or twisted) line instead.
