The Ossium Rotator from Quasar Science acts as a mini-grip head, providing the most flexibility in positioning lights or batteries. Made for the Ossium Grip system, it can be screwed directly to the Ossium Rail, Slider, or even the Battery Plate, allowing batteries to be attached to any 5/8" or 3/4" rod. Two of the Rotators can be screwed together back-to-back, providing two swivel points on two separate axes.
