5.0 EVA Rigging System (cont’)
5.23 Use of Two Standard Grids
Two EVA-SG standard grids may also be used with an EVA array, one attached to the upper module and
the other attached to the lower module, acting as a pull-up grid. This is a way to achieve extreme down
angles, such as might be encountered in a distributed arena system. Figure 18 shows this configuration.
When using two grids in this fashion, the angle between the suspension lines must never be allowed to
exceed 60°. Do not use EVA-EG extended grids in this application. For overall down angles of
approx. 45° or greater, use the second-to-last hole of each grid. For overall down angles of less than ap-
prox. 45°, use the second-to-last hole on the bottom grid and any hole forward of second-to-last on the
top grid.
