I have a replacement bimini from PontoonStuff that's okay, but the mounting hardware they included was absolutely terrible. My bro-in-law's new boat had mounting hardware much like these, and I realized I could replace the hardware on mine.I spent time looking for these and finding some that were actually in stock. I happily installed, but you should be aware of two potential problems.Problem number one: these require spacing underneath them. Without spacing, the release mechanism gets pressed into the railing you're mounting them to, and you can't release the knob part. I added a flat washer for each bolt, and that problem disappeared.Problem number two: You'll also (probably) need to add (or replace) a fitting on the end of the bimini tubes, something with a flange shape that fits into the upper part (the part that releases). Even finding that part in the proper size for my square bimini tubes was a challenge. But to add to it, the thickness of the flanges on the parts I found was actually a smidge wide for these parts. So you may have to be creative to get everything to fit.In spite of that, I'm very pleased. It took longer and more trouble to install than I would have thought, given how simple, but that was simply a matter of sourcing parts that would work. When done, this is a much, much better mounting system, and I really like it.

The casting of these is much more precise that other cheap versions. They only move in desired directions and do not rattle. Seems odd to almost pay as much for 4 of these as it was for the actual Bimini, but glad I did. Through bolted with 10 bolts. Very solid.

Good product and quick delivery, highly recommended.
