Safety chains and cables are legally required equipment, crossed under the coupler so they cradle the tongue if it drops. Class II chains suit trailers to 3,500 lbs; the Class III cable set covers trailers to 5,000 lbs. Both are sold in ready-to-fit lengths with their end connectors fitted. Replace any chain with stretched, rusted-through or repaired links rather than trusting it.
