I use these a lot, and to be honest, I was never able to effectively use the fold over end on the stanchions to wrap around the hand rail. So in the end this detail is clipped off. With it removed, it allows you to mount it so it would not show a fold over, and just connect it via solder. This detail is such an incredibly small detail, that just finding the right stanchion height (they give you several variations) is good enough (even for the eye of someone taking the effort to do this IMHO)
