Honestly, this wouldn't work. Unless your locks unlocked the opposite way of all other locks. Then you'd be brilliant because you created a lock that unlocks the opposite way. Otherwise, having six locks is just paranoid. They're going to break in anyway.
love this old barn door, adds lots of character to any project.great idea to use a barn sliding door system in place of building in a pocket door. I'd use this in our small master bathroom. Great space saver with some characture
