I received the hangers at 3PM on Saturday and had the door installed by 4. Now you have to understand that this is the only the second time I have installed a door.
The first time was a week ago using shims which took over 2 hours and that is when I gave up.
Now the hour that it took me cutting the shims out, cleaning up the mess, installing the Quick Door Hangers and installing the door, which went in without one problem, it was perfect the first time.
