This adapter allows you to directly connect your fifth wheel to a gooseneck ball, eliminating the need for a fifth-wheel plate. The adapter has a 20,000-lb. rating and has a fail-safe king pin adapter. It can be locked with a padlock and includes safety chains. To find correct size, line up the ball and your king pin hitch and measure from the top of the ball socket to the base of the pin box (allow for pin box adjustment).
Sizes: 12",14", 16".
