Desert Extrusion Cyclone CY155S3 .155" x315' Commercial Line Red, Made in USA - 2-Pack

What It Is

The Desert Extrusion Cyclone CY155S3 is a 0.155-inch diameter, 315-foot commercial-grade trim line for gas trimmers and brush cutters, sold as a 2-pack. It’s designed for heavy-duty clearing, commercial landscapers, or homeowners with thick weeds and overgrowth.

Fitment & Compatibility

Before buying, check your trimmer’s line diameter limit (most accept .155” or smaller; never exceed the max listed on your head). This line fits standard bump-feed, fixed-line, and universal heads—not proprietary spools. It’s aftermarket, not OEM-specific, so it works across brands (Stihl, Echo, Husqvarna, etc.) as long as your head accepts bulk line. Measure your deck size if using a trimmer mower attachment—this line is for handheld trimmers, not for mower decks. Verify your trimmer’s line capacity: 315 feet is a large bulk spool; ensure your head holds it (most hold 20-50 feet per reload).

Key Things to Know

• Quality: Made in USA from proprietary Cyclone copolymer—resists heat, abrasion, and snapping better than standard round line. Red color aids visibility.
• Installation: Moderate difficulty; requires spooling by hand or with a winder. Not pre-wound—you cut and load from the bulk spool.
• Gotcha: .155” is thick—may cause excessive vibration on smaller trimmers (under 30cc). Best on 35cc+ or commercial units.
• Durability: Outlasts standard line 2-3x in heavy brush, but can fray if hitting concrete or stone frequently.

Should You Buy It

Buy this if you run a commercial trimmer or have a large property with dense weeds, briars, or saplings. It’s overkill for light grass on a small electric trimmer. The 2-pack value is solid for pros, but casual users may find a thinner, cheaper line sufficient.
