Encontrei uma postagem de blog agora offline que apresenta uma solução usando slides de gaveta de extensão completa:
Assassino B. Design - Porta deslizante com hardware oculto: um experimento
I happened onto this beautiful solid wood old door that just-so-happened to fit perfectly over the opening for our bathroom linen closet. I was thinking of ways I could mount it, with exposed hinges like our vintage pantry door and office closet door...
But there wasn’t really enough room to add a swinging door in the tight bathroom space. I decided it should slide, but what kind of hardware? Should I do the barn door track like the one in our old home?
Drawer slides! I know, weird right? But so far it totally works! Our door opening was 24.5″ wide, so I purchased heavy-duty full-extension side mount 24″ drawer slides. They’re rated to hold 100 pounds, which is twice the weight of this door. I cut a scrap cedar 2×2 board to fit in the lower part of the door opening and attached it with pocket holes and 3″ screws. Then I mounted the drawer slides to the front of the door opening at the top and bottom, and to the back of the door. It took a lot of fighting and fumbling with it to get it up, but I was able to all by myself!
Ela menciona alguns problemas com os slides da gaveta:
One thing I (and you, if you look closely at that top left corner) noticed is that it does sag if left open. I’m also concerned about the potential of it falling forward off the rails. I’m thinking about mounting a bracket on the top to keep it in place, and possibly a small castor on that lower left edge.
