You will need to peel the uth back a little and just push it in, I have done it multiple times and have even moved them to other enclosures. Just barely peel it and push probe in and press uth back into place. You don't want probe inside bc snake can bump it and then it would be just like the uth wasn't even on a thermostat.

I will tell you I own quite a few of those zoomed thermometers and after I got a ir temp gun and acurite 00891 I realized they were off by 5-10 degrees on some. Not one was under 5 degrees off. That was my experience with them and all the thermometers I have used labeled for reptiles. Also I would monitor your thermostat closely. I had 2 that were very in consistent, they were set at 90 and would drop 5 degrees and heat back up to 93+ and then drop 5 degrees again and go up sometimes only 2 degrees sometimes to unsafe levels before it shut off again so my experience with them were not good so I switched to lamp dimmers until I bought a reliable one. I can't say the same will happen to you but pay close attention. I would order the inkbird itc-308 from amazon, it is only around $30-40 and will only drop 1 degree before it starts heating again making so your temps dont fluctuate a lot and just keep package and receipt to the zoo med thermostat and return it once you get the inkbird. Just my opinion.
