3. Repeat at least twice.

4. Once the marks are located, drill the panel from below with a torque-controlled screwdriver and a ¼” drill bit.

5. Drill every single mark.

6. We will use the measuring tape to mark another point, 10 cm apart from the previously drilled holes.

7. This is done to place the curb on the roof.

8. The curb should be aligned horizontally, so that the rib side get align over the ribs panel.

9. Once the curb has been aligned, an interior line must be marked on the inside and outside the perimeter of the curb. - NOTE: It will be necessary to re-mark a separate line 10 mm below the perimeter line on the bottom of the panel rib.

10. It is important to mark the cutting lines on, the top and bottom of the panel ribs.
