measured between the two Mounting Screw Holes on the
mounting surface.
3. Using a Phillips Head Screwdriver, screw the two
Mounting Screws into the surface, using the Mounting
Screw Hole locations marked in step 2 as a guide. Make sure
that you leave space between the head of the screw and the
wall.
