I-Beam Clamp Mounting, Sheet Metal Attachment .................................... DWG-1129110
Use this mounting method to mount a display to I-beams with a flange thickness of 3/16"
– 3/4". If flange is thicker than 3/4", longer bolts will be required at added expense.
Mounting hardware includes mounting channels; washer plates; I-beam clamps; 1/2-13 x
3.5" bolts; self-drilling screws; and 1/2" square nuts, flat washers, and lock washers. Refer to
Figure 11 and DWG-1129110 in Appendix B .
1� Position the display at the front of the beams, and lift it to the desired height.
2� Place a mounting channel against the upper rear flange of the cabinet next to each
beam.
3� Using the mounting channel as a template, drill two 9/16" holes in the upper rear
flange of the 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, and then push
the bolts through the holes in the rear flange of the cabinet and into the mounting
channel.
5� Place the two washer plates and 1/2" square nuts inside the mounting channel, and
loosely tighten the square nut onto the bolts.
6� Make final adjustments to the display position 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 cabinet for every beam.
