The sideboard extensions provide greater volume and thus more storage space.
Extensions are available at different heights, for NS3 vehicles at 400 mm when adding a volume of 2.2 m3, for NS5 at a height of 500 mm when adding a volume of 3.8 m3, for the NS6 500 mm increasing the volume by 4.6 m3. On the NS6 semitrailer, they are on the one hand supplied as standard equipment due to the combined sideboard. It can be opened in two ways.
The NS8 and NS13 vehicles are supplied with a galvanised extension at a height of 500 mm increasing the volume by 5 or, respectively, 4.5 m3. Extensions are a very popular accessory due to their functionality, stability and increased efficiency.
