Basic carrier for vehicles with open roof rails.


Tthe allrounder for the open roof rail. Fits on every rail - no matter if it's high, wide, thick or small. It connects unobtrusively and elegantly with every vehicle design.

Just as easy is its mounting on the roof rail. Out of the packaging - directly onto the roof. The Atera Signo Rail Rack fits perfectly.

The aluminium cross bar has a T-Slot that allows the usage of the full cross bar width. The T-Slot is used to mount carrier systems. The slot nut of the system adapter can easily be inserted into the profile and can be fixed from above.

This means: Atera products are developed and manufactured in Germany - more precisely in our development and construction department in Leutkirch in Allgäu, Southern Germany.
And if it doesn't say Atera on it, there is usually Atera behind it, because many carrier systems on our roads come from our company. The high functionality, good design and solid manufacturing of Atera products is appreciated by many well-known car manufacturers.)


This means that the carrier and load are secured in a frontal impact at 30 km/h and do not detach from the vehicle. A product that survives such tests has, in addition to the TÜV approval, another characteristic we are concerned with: quality. Moreover: never before has safety looked so good.
