Arnold Trimline Maxi-Edge .105-Inch x 165-Foot Commercial Grade String Trimmer Line

What It Is

The Arnold Trimline Maxi-Edge is a .105-inch diameter, 165-foot spool of commercial-grade nylon string trimmer line designed for heavy-duty trimming in gas-powered string trimmers and brush cutters.

Fitment & Compatibility

• Diameter: .105-inch – fits trimmer heads that accept line from .095-inch to .110-inch. Do not use in heads requiring .080-inch or smaller line; it may jam or overload the engine.
• Spool type: Bulk spool (no pre-wound cartridge). You must hand-wind onto your trimmer’s spool or use with a universal spool adapter.
• Brand/model: Works with most gas trimmers (Stihl, Echo, Husqvarna, Ryobi, Craftsman, etc.) but not with battery-powered models that specify only .080-inch or .095-inch line.
• Check before buying: Confirm your trimmer’s line diameter in the manual or on the head itself. If your head has a “load from side” or “bump-feed” mechanism, verify it can accommodate .105-inch line without binding.

Key Things to Know

• Quality: Multi-sided “Maxi-Edge” shape cuts through thick weeds and brush better than round line, but it’s louder and more prone to vibration than standard round line.
• Installation: Moderate difficulty – hand-winding 165 feet takes 10–15 minutes. Use a line winder tool or drill adapter to avoid tangles. Overfilling the spool will cause feed jams.
• Gotcha: This line is stiffer than .095-inch line; it may not feed well in older or worn bump-feed heads. If your head struggles, try soaking the line in warm water for 10 minutes to soften it.
• Value: 165 feet is 3–5x more than typical retail spools, making it cost-effective for frequent users.

Should You Buy It

Buy this if you have a gas-powered trimmer with a .105-inch-compatible head and you regularly cut thick weeds, briars, or overgrown grass. It’s overkill for light residential trimming or battery-powered trimmers that specify thinner line.
