Hitch Ball And Trailer Coupler - Centurion Ri257 Owner's Manual

HITCH BALL AND TRAILER COUPLER

Most boat trailers have a coupler that connects to a hitch ball attached to the
towing vehicle's hitch. The trailer hitch coupler must always match the size of the
hitch ball. The correct hitch ball diameter for the coupler is usually marked on the
trailer coupler. WARNING! Never use a hitch ball size or rating that does not
match the trailer coupler specifications.
