A plug for insertion into a through hole of a king pin coupler plate of a trailer includes a body defining two opposite axial directions and having a cylindrical, circular and continuous outer surface defining a perimeter. A plurality of pliable ears extend from the outer surface. The ears are each individually aligned in the axial directions. The ears each have a width that is less than ten percent of a distance around the perimeter of the outer surface of the body.
