I'm trying to determine just how wide the return would be once "attached" to the desk. If I read this correctly, it would be approximately 75". I need a return that is approximately 28" so that when attached to the desk, it would be approximately 56" side. The office is small. I want to face the door – not the wall. However, if the desk faced the wall, I could have the return face the door, so I would feel I had a little more privacy. And obviously, I would want the return to have a privacy panel, like this one does.
