Height and Width of Rhino Rack Vortex Crossbars

Can you please give me the outer dimensions of the Heavy Duty / Vortex bars? I believe they are the same. I bought a vehicle with what appears to be these bars on it and i want to get the Rhino Rack multi purpose holder so i want to verify the size to make sure it will fit. I know they make a universal clamp style but id rather get the one made for the bars since it looks cleaner and is cheaper too
