8 Mechanical Installation
1. Position the scoreboard at the front of the beams, and lift it to the desired height.
2. Place a C-channel against the upper rear flange of the scoreboard next to each beam.
3. With the C-channel as a template, use a

of the scoreboard cabinet where the rods will pass through. The rods should be as
close to the beam as possible.
4. Push the rods through the holes in the rear flange of the scoreboard cabinet and into
the C-channel, and then thread 1 /

hex nuts.
6. Make final adjustments in the positioning of the scoreboard to ensure it is flush and
level, and then firmly tighten all of the 1 /

" hex nuts.
7. Repeat steps 2-6 for the lower rear flange of the scoreboard for every beam.
