I used this to fit a custom barn door that was a little thicker than the stock door. I liked being able to mount it to the panel (my hardwood floors don't have holes), adjust the casters to fit my door, and make sure the door was vertical. I had a little trouble getting it really tight where the roller wouldn't be fully vertical and that would bind the post and make it difficult for the door to slide. Widening the opening solved the problem somewhat and everything works fine, although the barn door now has a bit of play.
