The descriptions of the products of Mengs are extremely poor. They are obviously translates literally from Chinese and you really have to look closely to understand the meaning. This jig is for example. not to bear that it is in the description to a complete panorama head in which a catch of 15 degrees can easily be switched. This panoramas are covered with all conventional wide-angle lenses. Closer degree numbers you need only when using telephoto lenses. A clamping Aracaswiss already exists, so you no longer have to fumble with screws.
