An action station is a trendy thing where the customer goes up to the counter and orders an item to their specification, or just to watch the chef. These normally use either induction cooking or heated stone surfaces so that no grease extraction ventilation system is required.
The post upright and / or mounting flanges are normally either 2" round or 2" square. The center line of the 1st post would then 1" end from 1 end. The pair represent the center lines of each segment's uprights.
In the example list that I posted, the overall dimension of the assembly would be 75" with (4) segment, but is not very practical.
With the list in hand, a fabricator could easily make and install all of the components and glass panels
