Designed to connect a trailer tongue to the towing vehicle, this Trailer Safety Chain is ideal for class I or II trailer applications. Made from zinc-plated steel, each chain is rust and corrosion resistant. 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. Features: Includes two S-hooks with safety latches Resistant to rust and corrosion Working load limit of 1300 lbs. Do not use for overhead lifting, do not exceed the working load limit
