A ANLEOLIFE 3-Pound ZT3 Pro Heavy Duty Diamond .105-Inch-by-846-ft Twisted Trimmer Line Spool,3-Component Tri-Extrusion 2.65-mm-by-258-meter Weed Eater String

What It Is

This is a heavy-duty, 3-pound spool of .105-inch (2.65mm) twisted trimmer line, designed for commercial-grade string trimmers and brush cutters. The tri-extrusion construction combines a wear-resistant outer layer with a flexible core, making it suitable for thick weeds, light brush, and edging along hard surfaces like concrete or stone.

Fitment & Compatibility

• Line diameter: .105-inch (2.65mm) – fits most standard gas trimmers and many high-end electric models that accept line up to .105-inch. Check your trimmer’s user manual for max line diameter; using larger line can overload the head or damage the engine.
• Spool size: 846 ft (258m) total length – this is a bulk spool, not a pre-wound trimmer head. You must cut and load the line into your existing spool or replaceable head. It does not fit “bump-feed” heads with fixed pre-wound spools unless you manually re-spool.
• Brand/model fit: Universal fit for any trimmer that accepts .105-inch line. No OEM-specific adapters needed. Works with brands like Husqvarna, Stihl, Echo, Ryobi, DeWalt, and Greenworks.
• What to check before buying: Confirm your trimmer head can be manually loaded (most can). If your trimmer uses a fixed-length pre-wound spool (e.g., some Ryobi 40V models), this spool is not compatible without swapping the entire head.

Key Things to Know

• Quality: The tri-extrusion process creates a line that resists breaking on impact (e.g., hitting fence posts or rocks) better than standard round line. Expect longer life than budget .095-inch lines.
• Installation difficulty: Moderate. You’ll need to cut lengths (usually 20-30 ft per refill), wind tightly onto your spool, and avoid tangling. A line winder tool helps but isn’t required.
• Common gotchas: The twisted profile can be slightly thicker than .105-inch at the twists, so it may jam in tight head slots. Test one piece before committing to a full spool. Also, the 846-ft spool is heavy and unwieldy—store it in a cool, dry place to prevent the line from fusing.
• Performance: Excellent for thick weeds and woody brush, but overkill for light grass. The .105-inch diameter also causes more vibration than .080-inch line on smaller trimmers.

Should You Buy It

Buy this if you run a commercial or heavy-residential trimmer (e.g., 30cc+ gas or high-torque electric) and regularly tackle thick weeds, blackberries, or edging against concrete. Skip it if you only trim light grass or have a small electric trimmer that recommends .080-inch or thinner line—you’ll waste money and strain your machine.
