Use your Rhino-Rack Heavy-Duty accessories on your vehicle with Thule or Yakima roof-rack tracks. Heavy-Duty square aluminum crossbars slide along tracks to accommodate gear. After the initial setup you can leave the bases in the tracks. Molded inserts help keep out dirt and provide a finished look when there are no legs and crossbars installed. To install a leg simply remove the insert. Once you’ve set up the bases installing and removing your roof rack is easy. The Quick Mount legs have an integrated trigger system that creates an easy tool-free installation. To install a leg in a base pinch and slide the internal triggers together. Lower the leg onto the base and slide the internal triggers apart to secure the leg in the base. Once the leg is installed in the base replace the cover and lock it to help secure the system to your roof.
