Dumb ??? Probe placment on backheat

So just got my new. Rack and it's backheat, my first professional rack and I have a ranco with a probe, so how do i get the probe to the tape in the back. Sorry for the dumb ??

Aluminum tape should work.

Oh, I havn't looked at it real good. Do I pull the top tub out and put my hands behind it to reach the flexwatt. It's a reptile basics 4 tub rack if that helps

There should be a hole to slip the probe through to attach to the flexwatt. With back heat just make sure you give it plenty of time to get to a steady temp before you fill it up with animals. You may have to set the thermostat quite a bit higher than your desired end temp goal.
