Safety Chains
Always attach chains between the vehicle and the trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for attaching safety chains and do not attach them to the bumper.
Always leave just enough slack so the rig can turn.
Never allow safety chains to drag on the ground.
