Considering a home theater "upgrade" for the house. When I was thinking about placement for the projector, I realized that the back wall of my living room is actually the wall to the Kitchen Pantry. Wife would not mind having a small rack for a projector in the pantry, and so I wanted to ask how you might go about having a hole in the wall with a glass optic to shine the projector through to the other room.
Through avsforums, I found that Edmunds non reflective glass would run me about $30-$40. However I'm concerned how I would finish up the hole, so that I don't end up having a literal hole in my wall!
Are there any ready to use items I could use to fashion a hole grommet/housing for the optic? (I was thinking a 3-4" diameter hole would be more than OK).
Considering this hole is going in the living room, it can't look too weird too. I welcome your suggestions!
UPDATE: In addition to the answers below, I found this product which is probably made for finishing a "hole": http://www.amazon.com/FastCap-Dually-Double-Sided-Plastic-Grommet/dp/B007CI3XL6
Also, cord grommets will work: http://www.amazon.com/Black-Desk-Grommet-Pack/dp/B000MM7PXG
