330ft 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 330-foot spool of 0.105-inch diameter trimmer line, designed as a replacement for Echo Black Diamond line (OEM parts 330095073/330095071). It’s intended for medium to heavy grass and weeds on gas trimmers and brush cutters.

Fitment & Compatibility

• Line diameter: 0.105 inch (2.7 mm). Confirm your trimmer head accepts this size; most standard gas trimmers do, but some electric models may require thinner line.
• OEM replacement: Matches Echo Black Diamond line part numbers 330095073 and 330095071. Not an Echo-branded product; it’s a third-party alternative.
• Trimmer types: Fits most brands (Echo, Stihl, Husqvarna, Ryobi, etc.) as long as the head can handle 0.105″ line. Check your trimmer’s manual for max line diameter.
• Built-in line cutter: The spool has an integrated cutter on the edge—ensures your trimmer head’s cutting blade is compatible (most are, but verify if you have an older or unusual head).

Key Things to Know

• Quality concerns: Rating is low (3.1/5) with only 5 reviews. Some users report the line is less durable than genuine Echo Black Diamond, breaking more easily in heavy weeds.
• Installation: Easy to load if your trimmer head uses a pre-wound spool. No winding required, but you may need to trim the line ends. The built-in cutter helps, but it’s not foolproof.
• Length vs. value: 330 feet is a lot of line for $26.99, but you’re trading lower cost for potentially shorter lifespan per strand compared to OEM or premium brands.
• Common gotcha: The line may be stiffer than expected, causing bird-nesting or jamming in some heads. Test on a small area before committing to a full spool.

Should You Buy It

Buy this if you need a large bulk spool for occasional medium-duty trimming and are okay with a budget option that may not match OEM durability. Skip it if you tackle dense, heavy brush regularly or want reliable performance—invest in genuine Echo Black Diamond or a higher-rated aftermarket brand like Oregon or Husqvarna.
