  • In the fixing points of the hook you have to remove or lift the tiles, so that you can place the hook without putting pressure on the tile.
  • Adjust the hook in height and laterally in order to position it in the middle of the ondulations of the roof.
  • Fix the profile for each panels row (using screws and nuts)
  • In order to connect more mounting rails in series you can choose several types of connections (i.e. connector plates, …)

 

 

 

Hereafter, according to the kind of panels used you have to position the sliding block swivel on the upper profile, pushing it till the click. You can fix the end clamp in the sliding block swivel using a screw. (see which one)
