Rhino-Rack has designed the Rhino Rack Backbone Rooftop Mounting System to work with Pioneer Platform as the quintessential rack accessory that allows a truck to take the extra weight and pressure without the risk of impeding the rooftops integrity. The new low-profile Rhino Rack Backbone mounting system is strong, supremely versatile, and blends perfectly with the look of any vehicle. Tailor fitted by application to your roof curvature allowing superior weight distribution allowing the Backbone mounting plates to accommodate up to 220 pounds of canoes, bikes, or luggage. With Rhino-Rack Backbone engineering, the Pioneer Platform reinforces the already strong design and allows you to carry the extra load. Rhino-Rack Backbone and Pioneer Platform combination have a static load rating of 704 pounds and a dynamic load rating 220 lbs. Made from non-corrosive materials to ensure it won’t rust in weather conditions or fade over time, meaning it will look just as good as your truck or SUV, for the life of the rack. Straightforward installation with some drilling required but the instructions take you through step-by-step and all the mounting hardware is included. Rhino Rack Backbone mounting system is a great-looking and unique way to mount a Rhino Rack Pioneer Platform to the roof of your vehicle.
