This photo shows one of the four corners of a Rhino-Rack Fit Kit. This kit allows you to mount a 2500 series Rhino-Rack on a vehicle without rain gutters or a factory rack. Shown here is the mounting bracket which clips onto the car's door frame (does not interfere with door usage). No drilling or tools are required, and the bracket has a rubber pad to protect your car roof from damage. The Fit Kit allows you to connect a rack foot pack and bars, making a complete roof rack system. This Fit Kit works with the Rhino-Rack 2500 series feet and aero cross bars.
