Inno XR feet are one part of a car roof rack. They are designed for vehicles with factory fixed points on the roof. When combined with a vehicle-specific Inno TR kit, these feet provide a base for load-bearing cross bars. The TR kit will connect these XR feet to your car's existing hardware - without drilling or scratching. This foot pack includes 4 feet that will accept Inno cross bars. They come with locks and keys for security, too. Backed by Inno's Lifetime Warranty. Manufacturer's part number: IN-XR
I received this last year and installed it within an hour. Good looking rack and appears to have quality components but I found the locking mechanism is not very secure. Only a plastic cover protects it from prying off. This is easily done and your rack could be gone quickly. I was disappointed with this design and thought I had installed in incorrectly but follow-up calls to manufacturer revealed it is built this way. I leave mine off if not planning on using it on my Mazda5. I also found it caused a loud annoying wind noise when installed alone. Ended up ordering the front piece to deflect wind noise but found that was very easy to steal as well. Just clips on. Maybe the other systems work better?
