Clik capo from Paige is on and off quickly with the same balanced tension the Original capo offers. Push the centre thumbscrew 'til it touches the neck, twist it a half turn or so and you're in business. To release, untwist a bit, then push the round button to completely release tension.
Width 2 1/4", Open Depth 1 1/8", Closed Depth 13/16". Works well on 1 3/4, 1 13/16, and 1 7/8 necks.
