This is the bar across the lane where the ball launches, not the ball return gate at the far top but this is near the spinner on the right side. Sometimes when the ball doesn't go all the way up the spinner, the ball will drop back through this area and land on the launcher again. I think I remember there used to be a gate on the bottom of this bar so the ball could only go back into play, not return to be launched again into play. Am I correct on this and if so, what is the correct name for this gate?
