Built two tub rack, have questions about if escape is possible

I just built this rack, eventually hold two tubs, these are 35QT tubs. The heating is nothing more than UTH on themostat right now, I might move over to the flexwatt setup eventually. My questions is about the lip in the tub, which I've taken a picture of, I'm not sure if my ball python can or cannot escape out. I know once he grows a bit, it won't be an issue, but I'm curious if he can even attempt to fit through that area. Other than that, the tub is pretty secure, it's a nice snug fit. Open to opinions of course, thanks!

I doubt he can get threw that. But you never know. But what he might be able to do is push the tub out. Try to put like a stopper so that the tub cant be pushed open by the snake.

if you are that worried about it slide some cardboard under the tub,
his head may be able to fit but i worried about the same thing with mine, it should be fine =]

Thanks a lot! I really appreciate the input!
