@ Lowhz: The LT25B is one of my favorite wall mounts (when I don't need a super low profile). But they do have the handle lever release at the bottom (where it bites on to the bottom of the bottom rail). I don't trust that in this particular installation. I'll look at the VMPL250

@ Justin: Yes. They want it flat and hugging to the 45 degree ceiling and I do too.

This area gets very, very, very, very windy and I fear the wind could get behind the panel and push it off.
