Mounting the Mast
Step-by-step Instructions for Mounting
the Mast on a Roof
1. Locate the center of a rafter where you want the mounting
foot to be located.
2. Hold the mounting foot in a position so the center line is
centered on a rafter.
3. Use a bubble level to make sure the center line is perfectly
vertical.
4. Use a pencil to mark the six holes in the mounting foot.
5. Remove the mounting foot and drill a 1/8" hole in the two
center line locations you marked.
6. Drill four 3/16" holes in the four outside corner locations you
marked.
