To help couple a trailer cab to the trailer frame a swivel box having a spring-loaded locking pin and a permanent hinge pin is coupled to a tongue that is used to couple the trailer cab and the trailer frame. The swivel box swivels or swings the tongue to a position to accommodate a misaligned trailer cab easing the coupling process.
