My opening is 36inches ... so the one that I ordered is 33.07 - 36.22 should fit right ?

My hallway is 36.5 inches at the wall, but only 35 inches at the floor molding. Which size do I get?

Measurements? None of the choices to purchase show 55" so where can I find as advertised?

On the listing page it says its 55.11 inches tall , as you drop down to get your width size none of them ssay they are 55.11 inches tall none can you
