I actually had all three of my Pro-Heat panels drop shipped to AP and had them install them. Not sure if they use the same bolts or not. I can't remember on my T25 but I know the two T8s have one hole in the ceiling of the cage with a bolt in it. I believe they router a long channel with one hole to feed the bolts through, lightly tighten the first, then slide the panel into place and feed the second bolt in through the ceiling and tighten them. Hard to describe without a visual component haha, and I'm only describing what I think it is that they do to install the panels. Hope this is helpful!
