These brackets are Genius! So genius that I highly reccommend even though I wasn't able to use them for my barn doors. I know I'll find them useful down the road, so I have no regrets. I bought two barn door kits which had pre-drilled holes for the hardware. The space between the bottom of the brackets and the top part of my door was just shy of being large enough. Drilling new holes for the door hardware wasn't an option. Luckily my husband was able to drill new holes in the mounting bracket to match up with the studs in the wall. In my opinion, the needed header board, if your studs don't line up, is unattractive and I was determined not to use one. I was trying to avoid asking my husband for help, as he was healing from an injury. Stumbled upon your youtube video in my research. Crazy GENIUS! So, people need to be aware if they're buying a kit that these brackets may not work. If you're drilling you're own holes for the hardware, these brackets are the only way to go! GENIUS!! Good luck to guys.
