Made from Type 430, 20 ga. stainless steel, these bars will give you many years of reliable service. Model 7535 fits the Genesis Silver A and Spirit 500. PLEASE NOTE: Weber makes many similar sounding models. Double-check the length of your existing bars before ordering to save yourself money, time and frustration.
