I bought the 922 butterfly nuts for a Thule EuroWay G2 to. They look very slightly different from the clamping nut supplied with the institution, but equally close. The nuts can be replaced easily. Do not be surprised if they are not complete in testing. The nuts must first be tightened and can not be further rotated. Then they can be closed easily. The security can I bad judge not seem to me however to be particularly high. Protect halt to rapid entrainment of the wheels, for greater safety, I would, however, still take an additional bicycle lock.
For a Thule load carrier is the perfect complement because the institution only a lockable clamping nut is.
