1. Position the scoreboard at the front of the beams, and lift it to the desired height.

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 /

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.
