About the MODEL

We call it "for banjo" but we're quick
to add "also fits most mandolins and bouzoukis." We
might throw in tenor guitar, and a number of other 4-string instruments. Until recently this model was the first choice for ukuleles. It does fit many ukes, especially baritones, but now we have a new model (9) specifically for ukuleles.
The C5, C5b, C5k, and C5a are the same size, shape and material (brass), and differ only in appearnace. The L5 (Lite) is made of aluminum and weighs half as much. The
S5 (deluxe) is made of stainless steel and features the improved roller design. It also has additional benefits
due to its geometry (learn more...).
fretboard radius
The great majority of banjo fretboards are flat.
Radiused banjo fretboards only came into use within the past 15
years or so, and still account for relatively few instruments.
If you're not sure whether your fretboard is radiused or not,
it probably is flat.
Because of the narrowness of the neck, gauge of
strings, resilience of the capo's rubber material, etc. the radiused
and flat model 5 capos can be used almost
interchangeably on some instruments. If you happen to get your
hands on the wrong one, there's a pretty good chance that it will
work OK, anyway.
