Step 7B: Affix the TRAPEZOIDAL CLAMP to the outer roofing with self drilling screws
When using the self drilling screws, two screws are placed per TRAPEZOIDAL CLAMP. In this
process, make sure you screw carefully to maintain static properties.
The enclosed self drilling screws 5,5x25 are approved for a sheet metal or aluminium thickness of
0.5 mm to 1.5 mm.
Important:
A drill with a diameter of 5.0 mm is mandatory to maintain static properties
