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 dual-ball head features standard 2" and 2-5/16" diameter trailer balls to fit two different size trailer couplers. 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 dual-ball head is constructed from high-strength forged steel and rated for a maximum gross trailer weight capacity of 10,000 lbs. for the 2" ball and 20,000 lbs. for the 2-5/16" ball. 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 dual-ball head is finished with a yellow zinc finish. This helps withstand rain, snow, dirt and road salt, protecting it from rust and corrosion.
