This is somewhat of a duplicate post, since I had posted a thread here about securing the bottoms of my sliding doors. However, I thought it might be a good idea to post a summary in this thread since it has to do with the same barn.
The main doors for the barn (all three sets of them) hang from their roller hardware. Unless the bottoms of the doors are somehow secured, they are free to swing outward when the wind blows through the barn. The most common way to keep them from doing that is to put a stay roller like the one below at the bottom of each door.
However, since the stay rollers are located at the outside edge of the door opening (it would be pretty inconvenient to have a couple stay rollers protruding out from the middle of the door opening where they could be driven over with a tractor or trampled by horses), they really only work to secure the outside corners. Without something additional to secure the inside corners of the doors, a strong gust of wind blowing through the barn could twist the doors pretty severely.
I got some good ideas about how to fix this problem in the aforementioned thread, and the solution I came up with was to bolt a PT board to the end of the slab with a rabbet cut along the top inside edge. Then I put a "Z" shaped metal bracket on the inside bottom corner of each door which protrudes downward into the rabbet. The bracket simply slides in the slot. I made the brackets from standard Simpson deck joist ties. I cut one side short and bent the edges slightly outward. Also, since the corners only need to be secured when the doors are in the closed (or mostly closed) position, the rabbetted portion of the board only extends for a couple of feet in the center of the door opening. Beyond that, the rabbet flairs outward until there's no wood remaining to hold the door in place any more. That keeps the groove from filling with water and provides a place for dirt and debris to exit the track.
Here are some pictures.
