-13 x 3.5" bolts;
self-drilling screws; and 1 /

" square nuts, hex nuts, flat washers, and lock washers. Refer to
Figure 8 and Drawing B-1129110 in Appendix A.
Note: I-beams must have a flange thickness of 3 /

". If flange thickness is greater
than 3 /

", longer bolts will be required at added expense.
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 9/16" bit to drill holes in the upper rear flange of
the scoreboard cabinet where the bolts will pass through. The bolts should be as close to
the beam as possible.
4. Slide a lock washer, flat washer, and I-beam clamp onto each bolt, then push the bolts
through the holes in the rear flange of the scoreboard cabinet and into the C-channel.
5. Place the 2 washer plates and 1 /
2
" square nuts inside the C-channel, and loosely tighten
the square nut onto the bolts.
6. Make final adjustments in the positioning of the scoreboard to ensure it is flush and level,
and then firmly tighten all of the bolts to 40 ft-lb torque.
7. Screw the self-drilling screws into the rear flange, snug up against the I-beam clamps.
8. Repeat steps 2-7 for the lower rear flange of the scoreboard for every beam.
