▶ Where required, secure boards/planks with adequate load-bearing

when subjected to loads.
Fig. 22 Fitting rafter anchors on the board/plank
The roof hook needs a little room for movement at the top edge of the
roof tile [1].
▶ If required, trim the top of the roof tile.
▶ It may be necessary to underlay the lower part of the roof hook with
boards/planks so that the roof hook lies on top of the tile to the front [4].
When the serrated washer [2] grips the teeth of the bottom part of the
roof hook:
▶ Tighten the nut.
▶ Use three suitable screws, to be provided by the customer,
(e.g. 5 × 50 DIN EN 14592) to secure the bottom part to the rafter
(boards/planks) [3].
Fig. 23 Securing the rafter anchor
To prevent windblown snow from entering:
