Use this mounting method to mount a display to I-beams with a flange thickness of 1/4" –
3/4". If the flange is thicker than 3/4", longer bolts will be required at added expense.
Mounting hardware includes spring nuts, I-beam clamps, 1/2-13 x 3" bolts, 1/2" flat
washers, and 1/2" lock washers. Refer to Figure 6 and DWG-1052565 in Appendix B .
1� Position a display section at the front of the beams, and lift it to the desired height.
2� Slide a lock washer, flat washer, and I-beam clamp onto each bolt, and loosely
screw the bolts into each spring nut. Position each of these I-beam clamp assemblies
as close to the I-beam flanges as possible.
3� Make final adjustments to the display section position to ensure it is flush and level,
and then firmly tighten all of the bolts.
4� Repeat Steps 1–3 with all display sections.
Note: When mounting four-section displays to three beams, mounting straps are
required on the rear channel along the middle beam to join the horizontal
sections together. Refer to DWG-1115341 for more information.
Note: For DSA (California) approved mounting to I-beams, refer to DWG-1064893 .
