Creating a rear-side cable outlet
With ducts that are fastened on the rear side to a solid wall or ceiling, you
can create a round opening on the rear side and use it as a cable outlet
(see Fig. 68).
The maximum opening diameter for BSKM 0711 and BSKM 1025 is
80 mm and 40 mm for BSKM 0407.
•
Create an opening on the rear side of the duct, e.g. with a step drill.
•
Carefully de-burr the edges.
•
Run the core drill hole through the masonry.
•
Pass the cables through.
•
Completely close the opening with a suitable fire protection filler. We
recommend the OBO system PYROPLUG
