Please watch fig. 6 for adaptation options. The
screws are constructed of stainless steel result-
ing in max. torque of 32 Nm. The adaption

safe construction.
Fig. 7: information for the screw connection
Lift up the roof tile. Place the hook portion of
the roof hook in the trough or in the flat surface
of the roofing tile. There should be at least
5 mm of space between the tile and the hook
portion. If necessary, place wooden shims at
the base plate of the roof hook accordingly. For
clay tile especially, we recommend placing a
sheet metal pantile that fits the shape of the
roof tile below the roof hook. Using a battery-
powered screwdriver, secure the roof hook to
the rafter (not the laths!!) with the supplied
three self-tapping anchoring plate screws and
washers. Other suitable screws can also be
used. Please adjust the battery-powered screw-
driver so that excessive stress is not placed on
the screws while they are being screwed in.
Select the correct friction clutch to prevent
screw heads from being broken off. If counter
lathing is present, use longer screws to achieve
sufficient fastening depth in the rafter (at least
55 60 mm). The roof hooks must be fastened
at the same height in the horizontal and vertical
axes.
If counter lathing is present, use longer screws to achieve sufficient fastening depth in the rafter (at
least 55 60 mm). The roof hooks must be fastened at the same height regarding the horizontal and
vertical axes.
Use the string and vial level for this purpose. For best results, fasten the roof hooks along the verti-
cal axis on one side and then on the other side. Then attach the string, which will show the proper
height for the roof hooks lying along its span.
always use three screws
