What do you think? Seem secure.. And there looks to be a space at the bottom for better heat transfer.

The dimensions are close to a 32 quart sterilite tub which I happen to be using now for once of my snakes.

I think this could be a potential "cheap" racking system. One tub ontop of another.. Flexwatt would be attached to the top of each unit so the upper tub gets the heat. Would this cause a problem for the lower tubs?

Just an idea. Your thoughts?
