The C-clamp of the RK-02 fits to virtually any surface of up to 7 cm (~3 inch) thick, and can be mounted horizontally or vertically. With this sturdy stand, you can easily position the Dino-Lite by bending the 60 cm long arm and adjusting the rotating head. The base of the RK-02 can also be rotated providing even more freedom and it can be fixed with the quick release fastener for use on uneven surfaces. The RK-02 gooseneck arm is the ideal choice to flexibly use any of the Dino-lite models, except the high magnification models.
