Constructed from durable Nylon material with extra mass to last longer, resist cracking and stay flexible. Nylon material is the ideal grade for the average trimming jobs around the yard.
Your trimmer line should be replaced every season. Old line can be weak and easy to break. It can also wear down from cutting thick weeds or against hard surfaces, causing you to not be able to cut as well. With Arnold Xtreme Professional Line, you can cut up to 3 times more area than economy lines, depending on cutting conditions and type of trimmer head.
