Mounting from the outside
1.1 Drill a 18 mm hole, deburr it and
protect it against corrosion. Loose part B,
push it upwards together with part C and
hold it tightly.

hole and decentralize it. Insert the plastic
fish-plates D of part C into the hole. Screw
on part B with a 20 mm open-end
wrench.
The ring nut B is tightened correctly,
if the upper edge of part A is at the
same height as the inner thread-bolt
