The CF3 Pro is a heavy-duty nylon trimmer line with a multi-edge profile that chews through thick grass and stubborn weeds without falling apart. It’s made with a three-component, tri-extrusion polyamide blend so the line stays sharp, resists wear, and runs cleaner than cheap round string. The size is straight forward: .095 inch (about 2.4 mm) diameter on a 229-foot spool — long enough to keep you going through big jobs without reloading every hour. The line’s unique shape gives several cutting edges per revolution so you get faster, cleaner cuts and less drag on the trimmer head. It fits STIHL nylon line heads and works in most common heads, so you’re not stuck buying a special spool for every machine.
Why crews pick CF3 Pro: it lasts longer, cuts tougher stuff, and keeps downtime down. On heavy patches and overgrown lots the line holds its shape and stretches spool life — that means fewer reloads, less frustration, and more work done before lunch. If you run a landscape truck or you’ve got a row of rental units, this spool covers a lot of ground before it’s time to replace it. Buy the CF3 Pro when you want a pro-grade line that won’t quit: heavy construction, rough edges, thick weeds, or long runs between reloads. No gimmicks — just a stout line that gets the cut done.
