Anybody keep snakes in stackable cages with hinged doors like these:

I have one that Duke lives in and I was thinking perhaps I'd switch some of my smaller snakes to this sort of cage but I worry about the bullsnake and the Dumeril's boa pushing at the verticle edge of the door and being able to wiggle through. Anybody have any experience with escapablity in this sort of cage?
