Barn Door was very easy to assemble. Hanging the door was a bit more challenging. Wish I would have known before hand that I needed a 1x4 header that was needed to purchase separately. The book said I needed a 1x4x78 3/4, but I actually need about 84 inches. So I will have to re-hang the header in the near future. I wish the long slide bar was wider so the wheels did not it the spacers. Overall, very happy with the door and it looks great. Not too difficult of an install for an amateur.
