my homemade boa cages. a cb-70 9 stack in the back left corner and two five stacks of the vision boa tubs. The only screws in them are in the casters on the bottoms of each. They slide together just like the visions. I have $1125 in all of them, minus the helixs, heated with flexwatt belly heat on each level. The boa tubs have 11 inch and the cb-70s have 4 inch.
