Octabank and Octabox is the same thing. Wescott calls it that, Profoto calls it Octa Softbox (Profoto has a 5' version). The same confusions go to beauty dishes, PCB/Profoto calls them beauty dish, while Elinchrom calls them Softlite reflectors.
That's what I thought.
Mine's only 4' though, which is still pretty big.
