Here in Canada home building supply stores like Home Depot, Lowes, Rona, etc sell outdoor stair tread made of recycled rubber in a variety of widths and lengths ... 3/4" thick with texture much like asphalt singles, perfect for preventing your Andersen Leveler from shifting, also useful for increasing it's maximum lift by another 3/4". I'd imagine home building supply stores in the US also sell a similar product.
