Intelligent roof rail assembly: Solutions by WITOL

Roof rails as an eye-catcher and functional element

Roof rails are a popular method of attaching sports equipment or other bulky loads to cars. In addition to the fastening, one criterion in particular is now increasingly decisive for the roof railing: the design. The railing can be individually adapted to the vehicle design and enhance it. From a practical point of view, it allows convenient transport of loads that turn out too big for the trunk.

The challenge here is that car roofs must not be deformed under any circumstances, not even by an attached roof railing. In addition, the roofs must be 100 percent leak-proof – this factor must not be influenced by a roof railing. In addition, extremely strong forces act on the railing and its screw connections in tight curves or during emergency braking. The roof structure must be attached to the railing in such a way that no additional safety risks arise for all road users in these hazardous situations.

Fastening solutions from WITOL

The fastening solutions from WITOL address this problem. They enable tight and at the same time stress-free fastening of the roof railing – both on car roofs with roof duct and on laser-welded models. The railing is firmly and securely connected to the supporting structure of the car body via several screw points.
