Tying Twine has minimal stretch and holds knots well making it ideal for packaging or bundling. It is mildew resistant, rot proof, resists oil, water and most chemicals. Warning: Avoid using a knot; splicing is preferable. 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. The working loads shown should never be exceeded. Additional care must be exercised when using this product under shock (stress, jerk) conditions. These conditions can reduce working loads by as much as 33%. Never stand in line with rope under tension; such a rope, particularly nylon rope, may recoil (snap back). Never use this product to secure large flat surfaces or objects, which could airplane or dislodge through buildup of air pressure. All ropes should be replaced if signs of wear, such as broken fibers, are apparent. Misuse can result in serious injury or death.
