Query: Easy to install.

It took about three minutes to pull off two torx screws, two phillips screws, hold the adapter in place, and put the four screws back in. I then folded the wings on the sides with a rubber mallet and this seems to have sealed it well. My only gripe is that it should have something akin to weather stripping to seal it though it's adequate as delivered.
