I will say that I am just starting out keeping multiple snakes. And I have made my own rack which I did not spend much on. I used wood I had here and most that was spent was for the flex watt and the thermostat. I am working on another to hold 28qt since my little ones are getting bigger the thing with the flex watt is you want to put foil tape down and then put the flex watt on top it does two things. 1. It keeps the tape directly off the wood. 2. It projects the heat upward so that the heat is not wasted.

That being said as long as your flex watt is properly wired and connected to a thermostat there is about as much chance of it catching fire as your fridge or computer or any other electronics in your house. Can it happen? Yes any of those things I said could start a fire that's why you need to make sure that you check on anything that you think is out of the normal and have your smoke detectors in place just like you would if you didn't have the snakes.

I hope this helps and does not come across as anything else but trying to help.
what kind of wood did you use??
