I looked at a magazine issue from around fall 2014. It talked about using a barn door to make sliding doors in a hallway over a kitchen or bedroom. Instead of making a barn type door, I would like to use the existing bedroom door that I already have. I would like to know if my existing bedroom door would be ok to use as a sliding door which would slide from outside of the bedroom. I would attach the bars at the top as indicated in the magazine, in the hallway over my bedroom entry and have the door slide open and close on the top metal bar. I also would like to know if the door could be locked from the inside once is it installed as a sliding door. Thanks.
