We acquired an entire collection, all racks were working & holding snakes when I unplugged them, 3 weeks ago, I have my own racks & don't need these extras, all have belly heat & thermostats, it's the responsibility of the buyer to check the heat tape & wiring before use. I will be listing several racks & an incubator as I have time to wipe them down. 
Black Rack.. measures 36x18x19 .. includes 3 tubs, thermostat & belly heat  $250
White Rack is homemade & heavy, measures 36x19x33 includes 5 tubs, thermostat & belly heat $200 
Both of these racks stack nicely. Both for $400 OBO
