Mechanical Installation 11
3.4 Ad Panel Mounting
The installation uses C-channels; clip angles;
1
/
2
-13" threaded rods; and
1
/
2
" square nuts, hex
nuts, lock washers, and optional spacers similar to the clamping mounting method above.
Refer to
Figure 8 and Drawing A-52187 in Appendix A .
Mount the ad panel(s) as follows:
1. Use the width of the beam to determine which hole combination to use for the bolts.
Be sure to keep the bolts as close to the beam as possible.
2. Using the clip angle as a template, use a
9
/
16
" bit to drill holes in the upper and lower
rear flange of the ad panel where the C-channel supports will be placed.
3. Position the C-channel inside the ad panel cabinet along the upper and lower rear
flanges as shown in Figure 8 .
4. Place
1
/
2
" square nuts inside the channel and thread the
1
/
2
-13" rods through the
C-channel, rear flange of the ad panel, and spacer (if used).
5. Lift the ad panel into position with the rods still in place.
6. With the threaded rod straddling the beams, place mounting angles over the ends of
each pair of bolts and secure with
1
/
2
" lock washers and hex nuts.
7. Make final adjustments in the positioning of the ad panel.
8. Make sure that the threaded rods are perpendicular to the ad panel, and tighten all of
the
1
/
2
" hex nuts.
Some ad panels have back sheets that must be removed before the display can be installed.
After marking and drilling holes in the upper and lower rear flanges of the ad panel, remove
the back sheets above and below the hole locations. Position the C-channel inside the cabinet
and attach the square nuts to the threaded rods as described above. Be sure to replace the
back sheets after placing the square nuts inside the channel and threading the rods through
the holes in both the upper and lower rear flanges.
