Purchased these for an old trailer I was refurbishing. They seem to be good quality and were easy to install.

These worked perfectly for my seadoo. The channel section is beefy enough, and I like the nubs on it so that it doesn't slip down on the trailer after it is mounted in place.

These work well with the 10" ones I also purchased. Good quality and come complete with all bolts and brackets.

Very fast shipping. One of the threads on the u-bolts were messed up I called them. As soon as I finished what I had to say he said he will send out new ones and got that in 2 days. Absolutely best customer service I've seen in a while
