What is the part of a round patio table that supports the legs?

I've always heard it called the frame of the table.

Metal frame, it goes around the outside of the table top.

Hello. These graphics might give you some clues. Hope this helps. It looks like it’s called a skirt or an apron and some pieces of furniture.

the base is what I call it or frame here is info

Hi! I've always called it the base or frame. The hole is then actually in the tabletop.

Frame.

Thank you for further explaining, I think the problem is that these tables are made by different companies and in different styles, therefore it is not an easily replaceable part. You would have to contact the company to see what they can do for you, maybe suggest a retailer who carries this part. I would have to call it the circular leg connector between the underside of the table and the floor.

A thought would be a couple of things, replace the base of the table, that way you'd have all new underneath it. Or if the table base is in good enough shape, find a welding shop and have them fix it.

Here is a link to ring and cap sets, in case I am off base (non intended):

A picture with an arrow would have been very helpful.

I'd call it the base or frame

Have you tried looking for a diagram of one from directions to put it together? That should tell you..... If you bought a table and it's damaged, just take a picture of it to send to the Mfg. to get a replacement.

Leg support.....

It sounds like you have it under control now. Sometimes, DIY is the best. It's so hard today with so many different terms used for part names as others have said. Glad you worked it out.

Is it a specific part you're looking to name? It's the table base as a whole under the top. If you do an image search on Google, you might be able to find drawn assembly instructions that list part names.
