$32.49

Twisted Square Design: Provides four sharp cutting edges and an aerodynamic shape that reduces line flutter and "vibration noise."
Maximum Cutting Efficiency: Slices through thick vegetation with 41% less effort than standard round line, significantly increasing productivity.
Professional Grade Durability: Engineered from premium high-grade nylon to resist fraying and withstand heavy contact with fences, rocks, and curbs.
Fuel & Battery Efficiency: The aerodynamic twisted shape reduces engine drag, leading to better fuel economy or extended runtime for cordless tools.
Heat Resistance: Designed to minimize "line welding" and sticking within the trimmer head during high-intensity, high-heat operation.

Commercial Landscapers: The premier choice for crews tackling overgrown properties, roadsides, and heavy brush.
Large Acreage: Ideal for property owners managing thick-stemmed weeds and extensive, woody fence lines.
High-Powered Trimmers: Optimized for large-displacement gas trimmers (30cc+) that can handle the weight of a .105" line.

The ECHO 330105071 Black Diamond™ Line is a universal-fit product designed for high-power equipment:

Gas Trimmers: Fits professional-grade gas trimmers including the ECHO SRM-3020 or SRM-410 series, as well as heavy-duty models from Stihl and Husqvarna.
High-Capacity Heads: Works best with Speed-Feed® 450, ECHOmatic® Pro, and heavy-duty fixed-line heads.
(Note: Verify your trimmer head can accommodate .105" diameter line before use.)
