.105 100' Ballistic Line

What It Is

This is a 0.105-inch diameter, 100-foot spool of ballistic-grade nylon trimmer line designed for heavy-duty trimming and brush cutting on gas-powered string trimmers. It’s intended for commercial or demanding residential use where standard line wears out quickly against thick weeds, briars, or light brush.

Fitment & Compatibility

Before buying, measure your trimmer’s line diameter spec—this 0.105" line fits most medium-to-large gas trimmers (e.g., Stihl FS 90, 94, 111, 131; Echo SRM-225, 2620, 266; Husqvarna 128LD, 129L, 324L). Check your trimmer head’s maximum line diameter: some heads cap at 0.095" or 0.100". This line is aftermarket, not OEM Ballistic brand, but matches OEM specs for those models. Also verify your head is bump-feed or manual-feed compatible—this line works with both but is stiffer than standard, so it may not load well in tiny or high-speed heads. Measure your spool’s capacity: 100 feet will fill most standard spools 2–3 times.

Key Things to Know

• Durability vs. standard line: This ballistic nylon resists fraying and snapping much longer than cheaper round line, especially on rocks, fences, and pavement.
• Installation tip: Soak the line in warm water for 10 minutes before loading to reduce stiffness and prevent kinking in the head.
• Common gotcha: Do not use on lightweight electric trimmers (0.065"–0.080" heads)—the line is too thick and can overload the motor or damage the trimmer head.
• Performance note: Cuts aggressively but produces more vibration than thinner line; wear gloves and ear protection during extended use.

Should You Buy It

Buy this if you have a mid-to-large gas trimmer, regularly clear thick weeds or brush, and want a line that lasts significantly longer than standard options without breaking the bank. Avoid if you run a small electric trimmer or need a flexible line for light, frequent edging.
