My First Snake Rack Ever!

Also you might want to install shelf support strips on either side, it makes for a sturdier shelf under each tub.

Looking at the tub sizes used and depending on the heat tape used it may work with a central notched shelf support as well. I agree it is a good idea though.

Also how are you planning on "locking" the tubs in to avoid accidental opening? I used corner blocks swiveling at one end. Then again I have neither cats nor children.
