It left us with a huge gap on the side. Our door measures 24”x2, hence I bought the 48”. There should be an instructions that we have to choose size bigger than the door way. As when the two doors overlapped, we’ve lost almost 6” of the original door size. Now, I have to buy the 60” rail and two 28-30” doors that when it goes up, it will just fit my 48” wide door way.
