Just a quick tip - If you are fixing some brackets to the frame and some to the wall - it is important to not measure from the frame across to the wall as this will 'Cut The Corner' and give false measurements. An example would be Point A and Point D are on the wall outside of the frame and Point B and Point C are on the frame. A dead straight line from A to B would not be parallel to the wall as it would cut across the frame. It would lead to a pole being made to wide for your space.
