I have a 83" width closet so I used two 72" closet doors. Basically, it is 3 doors on 2 tracks
However it is weird because the opening is way too small: 83-72 = 11" It is because the front two doors are on the same track which is taking 72" space.
Here is the track
Is this installation done right?
This is the door I bought
I got two of them
