The CompactVario offers flexible elevation for almost any span width.  It is used especially to bridge bigger purlin distances.

This construction is designed in such a way that no drilling has to be done on the construction site and a wide range of fastening elements for different roof systems is available.

Flat roof systems that are designed without a perforation of the roof covering have to be secured by sufficient loads against wind suction, tilting and sliding.  The CompactVario system offers considerable advantages as due to its favourable geometry, considerably lesser loads are required than in the case of single row arrangements.

There are various weighing options available for non penetration of roof membranes, ie. Soltub, Solrack and Solcube.  These are available in different sizes and the loading can be carried out using gravel, concrete block or the like.
