• When it has been verified that there is no wiring or plumbing
in the wall behind the mounting position, use the plate itself
as a drilling template and mark with the pencil the centers and
outlines of the mounting holes. A spirit level can be useful to
assure that the mount is properly leveled.
Figure 31. Drilling the mounting holes.
• Drill the six holes, using a drill or percussion drill with a bit
appropriate to the substrate material (masonry/concrete, wood,
steel etc.) with the appropriate diameter and to the appropriate
depth for the anchor type being used.
• Once the six mounting holes have been drilled, clear them of
residue and verify the appropriate depth of each.
• Place the mounting plate against the wall and align the four
mounting holes centered on the drilled holes.
• Insert the six screws or anchors directly through the mounting
holes in the plate, tightening the screw anchors with your fingers
sufficiently to keep them in place.

• While holding the plate in place, use a socket wrench or a power
screwdriver to tighten each fastener gradually, alternating
diagonally opposed fasteners in an "X" pattern until each holds
the plate to the wall. When using a power driver, keep it at a
low speed to avoid stripping the threading cut into the substrate
material. Once the washer or flanged head on each bolt is in
contact with the plate and the plate is against the wall, continue
tightening them only by hand.
