The DJI R Roll Axis Counterweight Set provides a counterweight solution for larger camera setups that can't be balanced on the roll axis of the RS 2 and RSC 2 gimbals, such as a Blackmagic Pocket 4K/6K with a long lens. Included are two 7 oz and two 3.5 oz counterweights, plus a tilt motor clamp for attaching them to the gimbal.
