i'm trying to help you get set up with proper equipment since your snake does not have adequate heat OR equipment. an RHP needs to be regulated by a thermostat as well and i don't think a Jumpstart will cut it (EDIT: nah it would work, but i use a Herpstat regardless)
the only radiant heat panel i know of that is mounted to a glass enclosure is user Mr Sully's quarantine tank with a Pro Panel RHP on top. my RBI RHP needs to be mounted with screws, which i use for my PVC.
I definitely planned on getting a more expensive thermostat for my RHP. It seems silly to have a top of the line heat setup with a not great thermostat.
but I guess what I've learned here is they're not compatible with glass cages. I shall investigate other options
