The Rhino-Rack Heavy Duty Fitting Kit is the essential adapter designed to bridge the gap between your Rhino-Rack Heavy Duty (HD) bars and the premium MasterFit range of cargo boxes. While MasterFit roof boxes are natively designed for more aerodynamic bars, this specialized hardware kit allows for a secure, robust connection to the wider profile of HD bars. Engineered to withstand the rigors of heavy-duty use and off-road vibrations, this kit ensures your cargo remains stable and locked down. Whether you are hauling gear for a long-distance expedition or professional equipment, this fitting kit provides the strength and reliability Rhino-Rack is known for, without compromising the functionality of your MasterFit luggage carrier.
