The Everbilt Diamond Braid general purpose Rope has excellent handling characteristics. Composed of Nylon and Polypropylene mix which gives it good durability. The Rope is an acid, mildew, rot, oil and gas resistant. WARNING: Knots reduce the strength of the rope up to 50%. Do not use this product for overhead lifting, support of human weight or athletic equipment or other situations where personal safety or valuable property can be endangered.
