Pride,
You have the same dinnette table as I, and Gary was correct about the "T" handle tightening piece. Take a look at the fitting under the table and you will see the way it was constructed, two pieces come together via a tightening bolt to secure the table to the post. Painted beige?
If it were my table the first thing I would do is contact the Catalina factory in Fargo, Florida and see if they have one available. I believe it is stainless. If they do not, unscrew that fitting off the table, take the piece to your local hardware store and try to find a long enough bolt that will fit. If your handy enough and can weld a small "T" at the end it will make removal of the table alot easier over using a socket wrench. But then, how often do you remove your table?
Easy fix.............
