Stens has simplified its trimmer line offering so you can make fast and easy decisions when it comes to the selection process. Stens is launching 3 distinctive trimmer line choices under the Silver Streak brand: The Core, The Fire and The Edge. Each trimmer line features new and improved labeling and packaging, a new multi-spoke design spool for additional strength, and netting to prevent the line from unraveling. The Core is an extremely durable line with a dual core, round shape and orange color. As a result of the extended durability, less line is used and less time is spent loading the trimmer head. The Fire is an efficient red, round-shaped line. It is manufactured with a proven formula of durable copolymer. The Edge is a hexagonal-shaped, green line. With 6 cutting edges, this line gives a clean cut that leaves a professional finish and a healthier lawn.
