I have been looking for something like this for years, I already had the WD shank and I wanted an adjustable ball mount to go on it. Couldn't find anything for less than $160 until this product came along. It is heavy, appears to be strong with good welds. It fits perfectly on my WD shank and it has way more towing capacity than I will ever need. It is well designed and made, fits on the shank with a rubber donut to take up any slack and keep it from rattling. The retaining pins are held in with a clip that will never fall off. E trailer shipped it promptly and it was well packaged

Works great, very useful for towing multiple trailers with different ball sizes and tongue heights.

@DiamondJ Yes, it is nice to just have one part with the 2 ball sizes so you don't have to go on the hunt for the other one when you need to tow a different trailer. Glad to hear things are holding up as they should Diamond.
