• If you look at the one I linked the long slot would fit over the little pip on the braze on and then you could put a nut and bolt through the hole on the hanger and the slot on the braze on. That way it would be adjustable and also stay straight. I've no idea if that's what the idea was, but it makes sense to me. Otherwise the pip is redundant.

  • Sounds like a much better idea than my suggestion.

    I couldn't think what the pip was used for except as some kind of stop, but it's much better suited to being a guide.
