WindDiffuser is a textured surface on the t-slot cover that disturbs the airflow better than a smooth surface, greatly reducing wing noise. The sophisticated BoxBeam aluminum extrusion creates one of the strongest load bars in the market. Using a vertical load test, the AeroBlade can sustain over 800 lbf of force. The new SwingBlade end cap pivots open to allow full access to the t-slot for easy accessory installs. The new SmartSlide is a molded measurement system providing a quick, no-hassle, tape-measure-free foot installation.SmartSlide also covers the underbar slot to improve aerodynamics and noise diffusion. Please look at the pictures of the actual item, and let me know if you have any questions.
