I'm looking to build a sliding door or wall that doesn't use the defacto "sliding door" parts, 2874 and 4511. These parts are almost usable for my design: they are thin and have a built-in stopper when using the corresponding "door rail" parts 32028 and 4510. Unfortunately, they are too tall.

Is there a technique to slide a plate, tile, or panel without resorting to using part 30586. I don't think I have the extra width needed by this part in my design.

  • What size of door are you looking for? What's the width of the wall?

  • @Uli: I'm building a railroad car using a 28x6 plate, so the wall length is constrained to 28 studs. Wall thickness is 1 stud, so the interior of the car has 4 studs of space. That said, I have things inside the car and so I was hoping to mount the sliding door on the outside and keep a low profile. Ideally, the door will be under 5 studs in height. I can probably increase the height of the car and then use the defacto sliding door, but I was interested to see if other alternatives exist. May 7, 2019 at 0:14
  • How many studs is the opening in the wall?

  • Fairly flexible at this point as I'm trying to see what is possible with the technique. That said, I would estimate the the opening to be between 4-6 studs. May 8, 2019 at 15:38

Have you tried using "bricks with groove" ?


  • Thank you for the suggestion! These may work, but I would have to orient them so that the studs align horizontally. I'll have to analyze my design to see if that is feasible. May 7, 2019 at 0:15
