Rooftop installation - General
The mounting rails can be extended by using mounting rail joiners.
One of the 3 screws of the mounting rail joiner set can also be used for securing
to a roof hook. For this, the U-rail remains centrally aligned; the screw can be
manoeuvred within the slot to the correct position above the hook.

Note:
Some tile shapes (e.g. flat tiles that are profiled at the top and bottom) must
be cut out in the area of the roof hooks to enable the fitted roof hooks to lie
correctly and to prevent the tile above from lifting up.
Recommendation:
We recommend the use of metal tiles below the roof hooks, particularly in
areas of high snowfall.
