Installing the Wall Plate on a Masonry Wall
Mount the wall plate on a brick, stone, or concrete wall by doing the following:
NOTE: The center of the wall plate does not need to be precisely aligned with the
center of the display above it because the speakers on either end of the wall plate
may still be adjustable on the wall plate.
1.
Follow steps 1 to 3 of Installing the Wall Plate on a Non-masonry Wall on page
5.
NOTE: Because masonry installation does not involve wall studs, position
the wall plate so that the mounting holes evenly distribute the weight of the
SB 33 A.
2.
Using a masonry drill bit, drill four pilot holes in the masonry wall at the locations you
marked in step one.
NOTE:
If you drill the pilot hole too shallow, the screw head might break off while
it is being fastened into the hole.
