Before making a hole, check carefully the following points :

and electrical cables.
Decide the piping hole position according to the location of
piping direction. Mark the desired drilling point.
When making wall hole, make sure to drill outwards at a
downward angle, so that the height difference between the
entrance and exit of the hole is at least 5-10 mm.

Measure the thickness of the wall from the inside edge to
the outside edge and cut PVC pipe at a slight angle 6mm
shorter than the thickness of the wall.
Step (3): Mounting Sleeve Into Wall Hole

After making hole, a sleeve must be mounted into wall hole
and its width to be equal to wall thickness to pass
