Our Replacement Rear Car Clips allow you to use the Car Back Carrier or Cargo Saddlebag on vehicles WITHOUT a roof rack. Replace lost Rear Car Clips or add Rear Car Clips to Carriers that originally did not have them included. Add the Clips to the side straps of the Carrier and attach them in the gap between the vehicle’s roof and the rear hatch door. The coating on the Clips prevents damage to the vehicle.
