Q: 10. I would use this mount on a standing desk, but my concern is that it needs a good amount of clearance behind the desk for the arms. I only have about 3 between my desk and the wall. Would it be able to fit in that space without the monitors being too close to the front of the desk? Thanks.

A: I have a free standing desk and when the monitors are pushed all the way back they extend about 10 past the back of my desk. Where mine are at usually they are less than 7 . With that being said, if there was a wall behind my desk the arms articulate plenty and still allow a lot of flexibility. You could also only use 1 set of arms to reduce the range and not have the arms protrude beyond the back of the desk.
