This single track bypass barn door system is very well made and is very heavy. The instructions are very well written. It does not take long to put up once you figure out the size of your doors. Especially if your making your own like I am .my doors were not finished yet thats why they are not pictured. But I will say when putting them up put one side up at a time and use 2 people that and have everything marked .that will make everything go much easier and faster.The reason for four stars and not five.is that they did not come with the parts so that you can make your doors telescopic if you want.
