Shipping communication by seller good, Fed Ex not so much. The packaging was genius and well done. One punch size hole in box, saw no damage near it. The upper slideway for rollers at one end was too closed to go over wall profile supports and was hard to make it fit. After some work I got it in. It is very solid and heavy to support 1/4 inch doors and hard to manipulate. Spent much time aligning doors as you have to keep removing them to readjust. Lower guide impossible to glue with doors on.
