The door is only 77 inches long. Since it secures at both the top and the bottom, there is no way to install the door since my door frame is 80 inches.

The photo is of the door after I put it back into the box for return returning. You can see that it is only 77 inches.

The specs say that the door is 80 inches in height.

The return process has to be done with the manufacturer, so that is an extra delay to the returning process. I am in the middle of that process now.
