Abstract: A trailer safety chain assembly that is used in combination with a raised ball trailer hitch trailer coupling type of trailer attachment. The trailer safety chain is made up of two sets of chained strands that are linked between a center ring. The trailer safety chain is situated between a vehicle and trailer being transported and acts as an auxiliary trailer attachment in the event of trailer attachment failure. A mounting plate is provided on the vehicle, with a set of apertures provided that accommodate a set of inverted L-shaped hooks and a raised ball trailer hitch. The trailer safety chain is able to keep the end of a trailer tongue from touching the ground and can transport the trailer even in the event of complete trailer attachment failure.
