Echo 316105055 .105" Cross-Fire Trimmer Line

What It Is

The Echo 316105055 .105" Cross-Fire Trimmer Line is a premium, OEM-recommended replacement spool for Echo and Shindaiwa gas string trimmers. It uses a twisted, cross-section design for faster cutting through heavy grass and light brush.

Fitment & Compatibility

• Line diameter: .105" (2.7 mm) – fits trimmers that accept .095"–.105" line only. Do not force into heads designed for .080" or smaller line.
• Compatible models: Works with Echo SRM-225, SRM-230, SRM-260, SRM-2620, and PAS-225/260 power heads. Also fits Shindaiwa T230, T235, and T242. Check your trimmer’s manual for “Cross-Fire” or “Speed-Feed 400” head compatibility.
• OEM vs aftermarket: This is genuine Echo OEM. Aftermarket .105" line may be cheaper but rarely matches the cross-fire twist pattern or durability.
• What to check before buying: Verify your trimmer head accepts pre-wound spools (not bulk line). Measure your current line diameter with calipers – .105" is about the thickness of two credit cards stacked.

Key Things to Know

• Cutting performance: The cross-fire design reduces line breakage and feeds more consistently than round line in heavy weeds.
• Installation: No tools needed – spool snaps into Speed-Feed 400 heads. For older heads, you may need to remove the bump knob.
• Common gotcha: Do not use this line on electric trimmers or low-torque gas models – the thicker line can stall the motor or overload the clutch.
• Spool capacity: Each spool holds about 20 feet of line. Expect 2–4 hours of heavy trimming per spool.

Should You Buy It

Buy if you own a compatible Echo or Shindaiwa gas trimmer and regularly cut thick grass, blackberries, or light brush. Skip if you trim only fine grass – .095" line is cheaper and easier on the engine. At $70, it’s a premium buy for users who want OEM reliability and faster cutting without constant line breakage.
