Originally, our fifth string capo bar was eight inches long, and attached to the banjo neck with three mounting screws. About three years ago we remodeled the bar, a change which I'd considered for many years. I've noticed that I never capo the fifth string any higher than the tenth fret (this would go along with the regular capo being at the fifth fret) ...there simply is always a better alternative to capoing any higher than this. So for my own banjo, I made a custom bar which was much shorter (5.75"). Now we've made the shorter bar our standard size. Besides taking up less space on the neck (for you fellow thumb-wrappers), it offers the additional advantage of using only TWO mounting screws instead of three.
