Determine which is the through blind as shown in the diagram above. We generally recommend that the through blind is the main window or where you achieve the most privacy to stop vision down the gap between the butting blind.
Take the width measurement of the Blind 1 (run through blind)
Take the width measurement of the Blind 2 (butt blind)
Apply deduction to the Blind 2 (butt blind) see table below. The deduction of the butt blind allows the track to butt up to the through track.
