This thing looks great and looks like it is well constructed, but it wouldn't fit on a standard 2 3/8 pole. It looked like it would fit and I tried to force it. Now, I have it wedged onto the pole and the swivel won't move at all. I had tried so many times to get it to fit, that I messed it up so bad it couldn't be returned. So it is on the boat stationary now. I hind sight, I should have taken a dremel tool and made the opening bigger. It isn't coming off of the pole. I beat it on with a hammer and wood. It is only on about 3/4 of an inch, but it isn't going anywhere.
