MamaRhea, sadly, is right. There's no real way to keep things heated in an AP enclosure without the probe inside the tank. I have mine suspended under the RHP, like hilabeans's setup. No way for snake to pull it severely out of place, very little way for poop/pee/water to get on it. It's not the best but is better than the alternative. I do need it for ambient, or else I'd stick with heat tape. Someday I hope to have a designated snake room with a set ambient temp and humidity so I don't need the RHP, but that's a fair ways off.
Soda can tip is much appreciated! Now I don't need to wait for clamp shipping. Going to fix things up ASAP, and now I know for any future AP purchases.
On another, smaller note: I greatly appreciate how much help I've been been given (and how patient everyone's been with my stupidity). Thanks, all! I'll get Tapatalk and post a pic once I'm done so I can make sure everything is as good as it can be for my snake.
