In the case of steep terrain and difficult ground, it makes installation much easier to use a substructure that requires only a few support points and can also bridge large differences in height. In combination with the CLIP system, decking supports with an adjustment range of 25 to 225 mm can be connected to our system rails in various profile thicknesses with virtually no screws. In this way, it is possible to react individually to the given terrain and still guarantee a fast and stable structure.
