Ok, I got these today. Although I got them to work, they have to have the
crappies spring mounts I've ever seen. They took much coercing to make fit.
At least they are in and keeping air from pouring through into the attic.

They aren't gasketed where they meet the ceiling though; should I use caulk
around the perimeter?
