This is an amazing glass barn door with a soft shut.  You will need to have a wood support installed for mounting the door due to its weight.  My husband is a builder so he knew exactly what to do - see picture (wood above the door).  We are still in construction and wanted to make sure it would work so it's not completed yet but you will get an idea of the mounting.  If you aren't familiar with hanging this type of door, you will have issues.  Lot of time was spent mounting the door.
