In agriculture, construction and even military applications, pintle hitches are the trusted product of specialized towing. They are notorious for their high weight capacity and simple design. The basic pintle hitch is essentially a hook and loop, with the hook attached to the vehicle and the loop mounted on the trailer. Because of their simple design, pintle hitches are able to have thicker metal construction and more secure coupling. CURT has a wide variety of pintle hitches and pintle-style products to give you a complete solution for your heavy-duty towing needs. This adjustable coupler channel is designed to mount CURT lunette rings #48600, #48601 or #48660 or CURT channel-style couplers #25319, #25329, #25330 or #25328, allowing for easy height adjustment and trailer levelling. It features a formed, one-piece steel construction and boasts a gross trailer weight capacity of 12,000 lbs. (NOTE: Never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). It offers five different height adjustment positions with an overall height of 11-3/4".
