Abstract
A trailer coupler includes mounting wings which straddle and are welded to the outer sides of the webs of I-beams which form the A-frame tongue of the trailer. A tongue projects rearwardly from the coupler into the space between the webs and is welded to the inner sides of the webs to increase the load-carrying capacity of the coupler.
