Love thus product. Very affordable and fits perfect. I cinched it to bench with lashing straps from Harbor F. Rig a tool to turn wing nuts from PVC. After easy install, it's solid. Like it a lot.

Swivel action and makes my seats portable- PERFECT

I read many reviews on these little guys before purchasing them with the molded plastic Wise boat seats. I read how the clamps are hard to install and hard to turn the wingnuts cause they are placed in a hrad to get to area etc... After using them myself I think people are pretty particular about expecting ULTIMATE PERFECTION from everything they buy. I find it pretty easy to turn the wingnuts and only spent about 4-5 minutes to install the clamp onto my boat bench. I made extra sure to tighten it down really good, and haven't had to adjust it since. It creeks a little and made me nervous at first, but if tighhtened down really good it is super stable and has not fallen off. I have used the clamps with my boat seats about 5 times now and haven't had to adjust mine since the first time I clamped it on. It swivels 360 degrees and does everything I was expecting out of it. It is perfect for me as I have a smaller 14' boat so I can bring myself fishing, or 2 or 3 people and have the versatlity of being able to place the seats in various positions at any time to fit the need of the fishing party.

Good Sturdy Base

I'm pleased with this purchase. I swapped the wing nuts for hex nuts, added an aluminum angle retaining fixture both front and back to prevent slipping and topped them with mid rise seats. Easy to remove and re-install using a 9/16” deep socket on an extension in a drill. Wife approval was a plus.
