The door slides left to open. There is a minimum of overlap on the door across the opening. But that overlap is enough for us to place some tabs that engage brackets welded to the door frame.

If you look closely at the left bottom of the door fully open you will see a tab on the door itself engages the bracket on the door frame. This secures the door so it isn't loose to swing out into the door way if an animal or handler bumps the door.

When the door is closed the same bracket is engaged by a tab on the other side of the door to secure the door so it can't be kicked out into the aisle by a horse pawing at the door. Horses do that. They paw at a door or wall for attention, to make noise, just because they can most of the time.

The second picture shows the tab for securing the door when it's open below the tab that's engaged when the door is closed.

I also used the round barn door track in this installation. I prefer it over the standard square track because it doesn't damage so easily under abuse.
