Rotary 14730 Black Vortex Trimmer Line .105" x 185'

What It Is

The Rotary 14730 Black Vortex Trimmer Line is a .105-inch diameter, 185-foot spool of twisted trimmer line designed for gas, electric, and battery-powered string trimmers. It’s built for heavy-duty residential and light commercial trimming, with a vortex shape that reduces drag and noise.

Fitment & Compatibility

• Diameter: .105-inch (2.7mm) – fits trimmer heads that accept .095 to .110-inch line. Do not use in heads requiring .080-inch or smaller.
• Spool size: 185 feet – check your trimmer’s maximum capacity (most standard heads hold up to 50-75 feet; you’ll need to cut and load multiple lengths).
• Brand/model: Universal fit – works with most brands (Echo, Stihl, Husqvarna, Ryobi, etc.). No OEM-specific spool required; just feed line into your existing bump-feed, auto-feed, or fixed-head trimmer.
• What to check: Measure your existing line’s diameter with calipers. Verify your trimmer head accepts twisted line (some require round or serrated). Confirm the spool arbor size if using a pre-wound spool (this is bulk line, so no arbor issues).

Key Things to Know

• Quality: Twisted, heat-treated nylon – resists fraying and breaking better than budget round line. The black color adds UV resistance.
• Installation: Easy – cut to length (usually 20-30 feet per load), wind evenly onto spool. No special tools needed. Watch for tangling if winding too loosely.
• Performance: Vortex shape cuts through thick weeds and grass with less vibration and noise than standard line. Slightly stiffer than round line, so it holds shape better in heavy brush.
• Gotchas: .105-inch is too thick for most low-power electric trimmers (e.g., Ryobi 18V) – stick to .080-inch for those. May not fit some auto-feed heads that require a specific line profile (check head manual).

Should You Buy It

Buy this if you have a mid-to-large gas trimmer or a high-torque electric model and want a durable, low-noise line that handles heavy weeds without constant breakage. Skip it if you need ultra-thin line for light trimming or have a low-power electric trimmer that can’t feed .105-inch.
