Here you can see how the Thule Moab cargo basket mounts to your existing roof rack. It works with any Thule rack, as well as other brands and factory racks. The top of the M.O.A.B. basket has 2 of its own crossbars, so you don't lose any carrying capacity. These bars can be used to mount kayak racks, bike mounts (shown here), and other accessories. The M.O.A.B.'s load bars are standard Thule square bars.
