What if there was a hitch ball mount that eliminated the need for all other ball mounts? Whichever trailer you wanted to tow, this universal ball mount could be adapted to fit the job. Imagine never having to buy another ball mount for your hitch ever again. Sound too good to be true? With the CURT adjustable channel mount, that's exactly what you get. The adjustable channel mount is a highly versatile hitch ball mount option. It features a standard receiver hitch shank, a multi-level channel and a standardized trailer ball attachment, allowing you to easily tow various types of trailer without requiring you to keep an arsenal of ball mounts on hand. It also features a highly durable construction built to withstand the elements, and built-in anti-rattle features for smooth, quiet towing. This ball and pintle combination head offers versatile towing options. It features a standard 2-5/16" diameter trailer ball to fit any 2-5/16" trailer coupler. With its integrated spring-loaded arm, the ball-pintle combination can also be coupled to a 2-1/2" or 3" lunette ring (inside diameter). The entire head securely attaches to any CURT adjustable channel mount shank using hitch pins and clips #45925 or a hitch lock set #23556 for additional security (shank, pins and locks sold separately). For safety you can be confident in, each CURT adjustable channel mount design undergoes strict testing procedures. This model is constructed from high-strength forged steel and rated for a maximum gross trailer weight capacity of 20,000 lbs. This makes it an excellent choice for livestock haulers, large flatbed trailers, deluxe travel trailers and much more (never exceed the weight ratings of the lowest-rated towing component). CURT adjustable channel ball mounts are not only built for tough jobs, but they are also engineered to offer smooth, quiet towing. Built into the adjustable shank is an anti-rattle mechanism -- a rubber bumper that goes between the shank channel and the trailer ball attachment. This anti-rattle bumper greatly reduces vibrations and noise coming from the coupling point, providing a smoother, quieter ride for the road ahead. In the world of heavy-duty towing, harsh conditions and relentless exposure to the elements aren't uncommon. For this reason, the adjustable channel mount is finished with a highly durable carbide black powder coat finish. This helps withstand rain, snow, dirt and road salt, protecting the head from rust and corrosion. The trailer ball is given a chrome-plated finish for additional rust resistance.
