The EUFAB 16412 disappointed across the board! For my Thule Racks will not fit (Note lacking), since the ball is undercut on the shaft and then "hooks" the clamp of Thule. An angle freely selectable terminal position is not possible, but for the Thule imperative as the carrier builds deeper than the holder of the wall projects (distance from the wall is insufficient for parallel suspension of). The fixing material is best suitable for concrete walls and extremely bad to use. Universal plug with lock screws would be substantial suitable for all wall types. Rating: Poor !!
