Should I use my rough opening or finished opening when I measure? Measure your rough opening, the door will be custom made bigger to overlap your frame and your guiderails will mount on the face of your frame. That is why your need the headroom and sideroom requirements. The Model 650 at the selected height will require 15 1/2 inches of headroom above the opening and 4 inches of sideroom to either side for installation.
