Thanks man

Yes that is correct! There is a grove that goes from the back of the rack usually on the middle shelf and goes up 1/4 of the way. It might be a little different with the heat tape now that I think about it, because my heat cable sits 1/4 of a inch in front of that grove in it's own grove. I can try to take a of where my probe is set up.

Zoas are great!
