253ft 0.105" Trimmer Line Cutting String Replacement for Echo Black Diamond Trimmer Line 330095073/330095071, Fits for Medium to Heavy Grass and Weeds, with Built-in Line Cutter

What It Is

This is a 253-foot spool of 0.105-inch diameter trimmer line designed as a direct replacement for Echo Black Diamond line (part #330095073/330095071). It’s intended for medium to heavy grass and weeds on gas or electric string trimmers that accept this diameter.

Fitment & Compatibility

• Diameter check: 0.105" (2.7mm) – confirm your trimmer head accepts this size. Most standard residential trimmers use 0.080–0.095", while 0.105" is for heavier-duty models (e.g., Echo SRM-225, PAS-225, or Husqvarna 128LD).
• Line type: This is a round, serrated line with a built-in cutter (not a universal fit – the cutter is pre-installed on the spool). Works only on trimmer heads designed for pre-wound spools, not bulk line.
• OEM vs aftermarket: It’s an aftermarket replacement for Echo Black Diamond line. Compatible with Echo, Shindaiwa, and some Tanaka/Makita heads that use the same spool design.
• Measure your trimmer head: If your head takes a different spool shape or lock mechanism, this won’t fit. Check spool width and center hole size (typically 1" wide, 0.5" center hole).

Key Things to Know

• Buildup quality: Line is slightly stiffer than OEM Echo Black Diamond – may reduce flexibility in dense weeds but improves durability on rocky edges.
• Installation: Pre-wound spool loads in seconds; no winding required. Ensure your trimmer head’s spool retainer clips match this spool’s slots.
• Built-in cutter: The integrated blade on the spool works well but wears faster than separate metal cutters. Replace spool when cutter dulls.
• Noise/feed: Some users report slightly louder operation and occasional line welding in hot weather. Let the line cool between heavy passes.

Should You Buy It

If you own an Echo-compatible trimmer that uses 0.105" line and want a bulk spool for heavy-duty trimming without frequent reloading, this is a solid value. Skip it if your trimmer requires a smaller diameter (0.080–0.095") or if you prefer the flexibility of OEM line for lighter grass.
