Adjustable Double Diner - 3 Sizes

The height is listed as 20",but it seems like that’s the height at the top of the loop. What’s the maximum height the bowls can be set to?
Also, the description says wrought iron at the top, but at the bottom it says it’s stainless steel. Obviously the bowls are stainless but what is the stand made of? Thanks

Per the description: This adjustable pet double diner features two stainless steel bowls that fit securely in a sturdy frame made of Wrought Iron

I will ask about the max height of the bowls.

Ok, per the vendor: The highest it can be set to is 16 inches.
