Installed and using it in my boat. Heavy duty and seems to be standing up to heavy use.

Might need to make hole in floor bigger. I did, use a jig saw, so you dont damage bottom of your boat.

This is a great product. However, I ordered it thinking it had the plastic insert so it didn’t work with my seats. Easily returned for refund😀

Replaced my old cracked one with this new one. Same as original and works just fine. I am happy.

Works great and is perfect for the Attwood 2" wedge extension post. The picture is not quite accurate. The slot on one side is wedge shaped, not rectangular.

Works awesome! Great product! I put in my old 1989 I/O and one of the best upgrades I made.
