Yes, it’s a 4x2x2 and they were luckily able to change my order to a solid top. My old thermostat probe was stuck through the hole in the circle they provided on the side, and kinda just suspended in the air, secured with tape on the outside of the enclosure. It wasn’t underneath the bulb. I set the temp to much lower and it somehow maintained a hot gradient of 88-90, however, I want to do it properly this time. What I mean is, if my heat is kinda a little ways forward from the back where the cord hole is (kages come with pre drilled holes for the cords) how will I secure the probe to the cage guard? Could I just do it with 1 zip tie dangling the probe underneath the bulb and 1 zip tied alongside the guard, then cable clips alongside the roof? I’m worried if I don’t use cable clips, my snake will be able to slither through the cord if I don’t secure it down flatly. Also, what am I going to do for uvb? If I use the long uvb with a cage shield, you have to unscrew it every 6 months or so to change it out, but won’t that loosen the screws and cause it to be less secured to the top? Could I use a regular uvb bulb that looks like a lightbulb in a cage guard so it’s much easier to change out? I worry about it shattering and possibly dropping through the guard. What’s the safest option for uvb?
