I have searched through the DIY racks and it seems that this is never covered. I am going to heat with belly heat and I want to mount the probe on the middle shelf of a six bin melamine rack. My plan was mot simply cut a groove in the shelf so the 12" heat tape stays flush to the shelf. It is a Herpstat probe so it is pretty large. Any problems with this method? I just don't want the tube rubbing on it or potentially moving the probe.
