Installing the double-ended screws

WARNING:
Danger to life due to falling cylinder!
▶ Only screw double ended screws into a substructure with sufficient
load bearing capacity.
We recommend making a drilling template to ensure accurate vertical
drilling.
To create a drilling template:
▶ Drill vertically through the timber using a wood drill bit.

1. With a 14 mm drill bit, drill through the peaks of the roof tile.
However, do not drill into the timber below!
