All Curt hitches feature WeatherTite construction, which prevents rusting from the inside out by sealing the main body of the hitch. The receiver tube has an open back end to allow for easy cleaning and for dirt and moisture to pass through and not get trapped as is common with other brands of hitches. All Curt hitches come with mounting hardware and installation instructions. Curt is the only hitch company that mechanically de-scales all of the hitches before applying a thick powder coat finish, which is baked on for a high-gloss, smooth surface. Curt trailer hitches are simply the most attractive, most durable and toughest hitch.
