I used this barn door hardware for an opening between two interior portions of my garage.  The door was easy to install and the hardware provided works for most installations.  In my case, I had an thicker than normal door so the bolts depicted were substituted by me to fit this situation.  The bolts and screws provided with the kit are black to match the track and wheel frames.  The door glides very smoothly and the end stops on the track gently stop the door at each end of its travel.  Would work great for closets, pantries, and many other applications.
