STEP 5 – Use a measuring tape to center the plate
on the roof.
Step 6 – Mark the corners of the dish. This is used
later on to accurately lower the mounting plate onto
sealant.
STEP 7 – Mark all screw holes for drilling pilot
holes. Note that you don’t need to use the factory
holes, and can drill your own in the mounting
plate.
STEP 8 – The drill bit used to create pilot holes
must be smaller than the threads of the screwbolts
used…but the size can’t be too small or you could
crack fiberglass roofs. The size the drill should
be is the size of the shank of the screwbolt.
Self-Tapping screwbolts (as shown by the silver screwbolt in Step 8) are recommended for
installations because of their “cutting” edge. Pilot holes are always required, especially on
fiberglass roofs.
