thank you every one and yes I am looking for the ones with lids. We have 2 sets of racking in the basement that I would like to use as a rack but the shelving does not allow the levels to be close enough together to act as a lid to prevent a jailbreak. May still build my own rack at some point but would like to use the racking we have for a while. Trying to get all the info we can so we can set it up and build it right the first time. I know there will have to be tweaks here and there but would like to build the best setup for the snakes that we can.
