I'm finally a registered user! Has anyone seen or does anyone own the Pro Imager Vertical Masking Sysyem from Da-lite? I am mostly wondering how it looks cosmetically. I have only seen pictures which don't seem to help much in this regard. It looks as if the masking is gray in color and yet in the description it says the masking is black. If I get the Perm-Wall screen, will the masking system hide its ugly front snaps on the frame? And, ofcourse, does the masking system work well? Thanks in advance!
