I have 37 balls and 2 boas, the whole point of the rack is to not have to deal with tops. Why the hell wd I spend $360 on 9 sheets of custom ordered black melamine and then 2 days to build 2 monster racks, just to pull the bins out and deal with tops individually?????? Are you crazy. If you only have 3,4 or maybe 5 snakes sure use the tops. But you cd also just sit ur bins on the dresser with under the aquarium heat pads too. And save alot of time and effort.
Just saying.
