This was the product that got it all started for us back in 1974, and to this day it's STILL the only fifth string capo worth putting on a banjo. It operates on a lever principle, not a spring, so it provides sufficient pressure to fret the string without muting the tone. It slides on a slim, dovetailed bar which mounts flush to the neck, making it sturdy and unobtrusive. We strongly recommend that you have a luthier or repair person install your fifth string capo. Most places that work on instruments can mount it for you in just a few minutes. Or if you are handy with small tools, and not shy about working on your banjo, you could install it yourself.
