A ANLEOLIFE 5-Pound Heavy Duty Twisted .155-inch-by-759-ft Dual Core String Spiral Trimmer Line Donut,with Built-in Line Cutter

What It Is

This is a heavy-duty .155-inch dual-core twisted trimmer line, 759 feet long on a donut spool with a built-in cutter. Designed for commercial-grade or high-volume residential trimming in thick grass, brush, and weeds.

Fitment & Compatibility

• Line diameter: .155-inch (4mm) – fits trimmer heads that accept .155 max; check your manual or head stamp for line size range (common .095–.160).
• Spool type: Donut (bulk line), not a pre-wound cartridge. You must hand-wind onto your existing spool or bump head.
• Brand/model: Universal fit for any gas or electric trimmer that uses .155 line. No brand-specific adapters needed.
• Length: 759 ft – enough for 15–20 refills on a standard spool. Built-in cutter eliminates separate tool.

Key Things to Know

• Twisted dual-core design reduces breakage and delivers cleaner cuts on heavy weeds vs. round line, but it’s stiffer and may cause more vibration on smaller trimmers.
• Installation: Moderate difficulty – hand-winding 759 ft evenly is tedious. Use a drill with a winder or take your time to avoid tangles.
• Built-in cutter is sharp and works well, but be careful not to cut too close to the spool edge.
• Not for light-duty electric trimmers with small heads (e.g., 0.080–0.095 line) – the .155 may not fit or could overload the motor.

Should You Buy It

Buy if you have a mid-size to large gas trimmer or a high-end electric model, and you regularly tackle heavy brush or overgrowth. Skip if you only do light lawn edging or use a small electric trimmer – you’ll waste line and risk motor strain.
