Thanks Adam. I actually have scraps left over I can use for dividers since they don't have to go all the way. I just don't have them cut & installed yet as the priority is to get the snakes into the rack for easier/better husbandry. And as for casters, they're in the plan. But they're going to go on the one I build next that this one will sit on top of for 41 quart tubs for females. I think I could do it now though. Let me think on it. LOL
