I am looking at purchasing reptile basics 32qt sweater box tub this week. I know that both of my current snakes will fit just fine in them but the guy selling the rack also has a 1500g female that he is willing to part with as well. Is she too big for the Iris MCB-L sweater box rubs?

This would be my first rack. I just want to make sure that she would be ok in it before I worry about purchasing her with the rack.
