Thule’s AeroBlade Edge is an integrated foot/load bar with a low-profile, aerodynamic design for vehicles with a factory roof rack. The AeroBlade bars use BoxBeam construction, making them some of the strongest load bars on the market with a capacity of up to 165 pounds. In addition to their wing-like shape, the AeroBlades sport a textured surface that greatly improves wind flow so you get drastically reduced noise and much better gas mileage. The feet fit your vehicle’s roof rails without a fit kit and they’re T-track compatible as well.
