Mechanical Installation 9
Clamping to Verticals
An inverted channel mounting installation uses C-channels; clip angles;
1

-13" threaded
rods; and
1

2
" square nuts, hex nuts, lock washers, and optional spacers. Refer to Figure 6 and
Drawing A-55101 in Appendix A .
Mount the scoreboard as follows:
1. Place the C-channel against the upper and lower rear flanges of the scoreboard.
2. Use the width of the beam to determine the appropriate hole combination to use for
the bolts. The bolts should be kept as close to the beam as possible.
3. With the C-channel as a template, use a

" bit to drill holes in the upper and lower
rear flanges of the scoreboard cabinet where the bolts will pass through.
4. Place the
1
/
2
" square nuts inside the C-channel and thread the
1
/
2
-13" rods through
the C-channel, rear flange of the scoreboard cabinet, and spacer (if used).
5. Lift the scoreboard into position with the bolts still in place. Position the scoreboard
at the front of the beams with the threaded rods extending from the rear flanges.
6. With the threaded rod straddling the beams, place mounting angles over each pair of
bolts and secure with
1
/
2
" lock washers and hex nuts.
7. Make final adjustments in the positioning of the scoreboard.
8. Make sure that the threaded rods are perpendicular to the scoreboard, and tighten all
of the

" hex nuts.
