Darklab RPG Click Screw-on Vise Collet Connector by FK Irons

With the introduction of the safest adjustable cartridge grip, FK Irons now provides a way to use the RPG Click with screw-on vise style tattoo machines – the Screw-on Vise Connector. This patent-pending collet connector enables screw-on vise style tattoo machines, such as Inkjecta, to work with the RPG Click or any other standard back-stem style grips. It is a 2-piece connector, consisting of a chuck and collet, with easy installation and removal.

Please Note:  The Spektra Edge and Edge X do not need a Screw-on Vise Connector to use with the RPG Click.
