The RigWheels RA02 2-RigAxels are designed to be used in conjunction with the RigPlate (sold separately). These RigAxels allow for several different additional configurations that provide you with even more options for getting smooth camera movement with the RigWheels system (sold separately).
With the custom inline wheels (sold separately) attached to the ends, you can use these RigAxels to convert the RigPlate (sold separately) into a more robust tabletop dolly with a larger footprint. This is a suitable solution for larger camera setups. Moreover, you can pivot the RigAxels to get curved dolly moves. When used with both the RigPlate and RigWheels, they add a bottom bar to make a captive rail pipe slider.
These RigAxels and the RigPlate can be used together with the RailRunner configuration. Four 1/4"-20 holes allow for easy attachment of the RigMount (sold separately) and A-Cups (sold separately). In this configuration, the RigAxels can serve as mounting points for camera gear as well as stabilization outriggers when using the RigPlate as a camera mount.
