In my experience, those tubs aren't secure enough, at least not for an adult BP. I started off keeping my 1500 gram adult male BP in a tub with 4 latches, admittedly a cheap one. One night, I heard a pop. I looked over and one latch was undone. From in the tub, he put enough pressure to pop the latch. I put something heavy on top and ran out to buy 4 spring clamps to hold the latches down. He escaped anyway. I was puzzled because the clamps were still in place. So, I moved the clamps to the gaps between the latches. Only then did he stopped escaping.
