"moving the screen back and forth is quick and easy for fine tuning your screens placement"
"These Elite screen mounting brackets are essentially what you would expect. Nothing fancy, they are just mounts. Comes with drywall anchors and other hardware for optional mounting surfaces. Since I was going into drywall, my interest was in anchor strength. I didn't quit trust the included ones with my expensive 110 inch electric screen and ended up getting Togglers from Lowe's.
Brackets have a powder cost finish. I ordered the 12 inch and by using the included eye hook screws and wing nuts, moving the screen back and forth is quick and easy for fine tuning your screens placement."
