Adjustable ceiling vent for AC
There are a few things I'm surprised aren't standard equipment. One of these is adjustable ceiling vents for the AC that can be closed/adjusted. It looks like this is a common change people make on their units.
1. The current ones I have don't close, they only swivel. They are 7 inches in diameter, 1 1/8 collar, and 4 3/4 opening. I see there are several companies making after market units. Does anybody recommend one over another and know they will work on my Crusader?
2. How do you remove the ones already installed? I glanced at it and it isn't immediately obvious to me. There are three little notches/holes around the edge -- that may be involved in the removal process.
Any tips appreciated.
