I am looking at the slanted pan holder and trying to figure what you would put in there? If you have a cold condiments section on the side, you really don’t need the slanted pans. The pans are at quite an angle, it looks as if they can only be filled less than half way before product pours out. Also at that angle, if you don’t set the lid on just right, they will slide off into your steam table, something you don’t want when busy!
I would leave it off or request that it be a flat shelf for storage.
