Weed Warrior .065 in. x 50 ft. All Purpose Trimmer Line is scientifically engineered to be more durable than other residential grade trimmer lines. Impact modifiers are set within the nylon to keep your line from breaking away when trimming against obstacles as often as other products on the market. That means cutting more with fewer stops to get the job done faster. The .065" diameter is designed to fit most battery and electric trimmers and works with all brands.
