not only applies to the top enclosure in
an array column, but also applies to every enclo-
sure in an array column. In arrays where a pull-up
line is not used, the top enclosure is always the
limiting factor because it supports the most
weight. However, in arrays where a pull-up line is
used to achieve substantial downward angles, it is
possible that a lower enclosure could be the limit-
ing factor.

3.4 Complex Structural-Rating Analysis
For a complete structural-rating analysis, the
forces in each individual piece of rigging hard-
ware throughout the X-Array™ system must be
determined, as well as the forces on each enclo-
sure. Determining these forces requires complex
