This model capo is made specifically for the ukulele!
At a glance it looks like a banjo capo, but it closes onto a smaller neck, and accommodates a slightly wider fretboard. Tested on many brands confirms this capo is a perfect fit on all tenors, sopranos, concerts, and baritones ...except the occasional baritone with a very large neck. In these cases, the banjo capo will do the job.
