System variants

Roof tiles and roof stones

80% of all applications can be solved with our SingleHook 3S or 4S.

Even with difficult rafter spacing, you can build perfect solutions with CrossBoard or SingleBoard. For higher load requirements we offer the SingleHook Alpine. The SingleHook 3S long is installed for tiles with a larger overlap and can therefore also guarantee the use of the SingleRail for larger tiles. We offer special roof hooks for plain tiles or flat concrete roof tiles.

Our SingleRail system can also be installed with on-roof insulation by using different screws.
