Step 1: Mount Upper Frame to Wall
Scribe a horizontal line on the wall
showing the exact location of where the
top edge of the upper left monitor will be.
Measure down 9.1” (231mm) from that
line and scribe another horizontal line
showing where the horizontal location of
the first adjustable lag bolt will be (Figure
1).
Scribe a vertical line showing where the
top left side of the upper monitor will be.
Measure to the right 16.9” (429.3mm) and
scribe another vertical line showing where
the vertical location of the first adjustable
lag bolts (Figure 1). Mark the intersection
of the vertical and horizontal lines.
Measure 157.7” (4005.6mm) to the right
for the location of the second adjustable
lag bolt. Use a long level to
make sure the second
location is horizontally
aligned to the first lag bolt
location (Figure 1). Mark the
second lag bolt location.
Measure 76.9” (1953.3mm)
to the right for the third
adjustable lag bolt. Mark the
third lag bolt location (Figure
1).
Pre-drill the marked lag bolt
locations using a 3/16” or
5mm drill bit.
Install the first, second and third adjustable lag bolts to the pre-drilled holes
until the hex part of the bolt is flush to the wall. A deep socket wrench maybe
required.
Step 2:
Hang the upper frame to the adjustable lag bolts (Two or three people
required). Install the provided hex nut and flat washer, level upper frame then
tighten the hex nuts.
Use the frame as a template to mark the other locations of the adjustable lag
bolts. Use three (3) per vertical channel, two keyholes and the center hole
(Figure 2).
Loosen and remove the hex nut and flat washer securing the upper frame to
the wall. Place the upper frame back on the floor. Pre-drill marked holes using
the 3/16” or 5mm drill bit then install the other adjustable lag bolts until the hex
part of the bolt is flush to the wall (Figure 2).
