The Rhino-Rack 2in hitch receiver locking pin secures 2" receiver bike racks such as the RBC038 to the vehicle, reducing theft risk. Already included with the RBC038 but offered as a spare, this locking pin is a practical replacement or backup for rear hitch-mount bike carrier setups that use the 2" receiver standard.
