marked.
7. Fill all six holes with a small amount of roof sealant.
8. Use a wrench to loosen the nuts on the mounting foot so you
have easier access to the mounting holes.
9. Hold the mounting foot over the holes so the top part of the mast
will rotate and point straight up.
10. Use two 5/16" x 3" lag screws in each of the center line holes to
attach the mounting foot to the roof. Secure the four outside
corner holes with four 1/4" x 2" lag screws. Securely tighten all
six screws.
11. Seal the mounting foot with roof sealant. When applying the
sealant, make sure you seal the areas shown in the figure below.
