5.0 EVA Rigging System (cont’)
A second spreader bar, EVA-GXB, is available (sold separately). The second spreader bar is used when
two front-to-back pickup points are desired/required. Figure 16 shows an EVA-SG2 grid with a second
spreader bar. When two spreader bars are used, one is attached to the extreme front hole positions in the
side arms and the other is attached to the extreme rear position. This gives the most control over the verti-
cal aiming of the array. Note that the need to maintain sufficient load on the front spreader bar to maintain
rigging tension will diminish the amount of down angle available with a standard grid. For this reason the
EVA-EG2 extended grid is probably a better choice when using front-to-back pickup points.

5.22 Extended Grid with or without Second Spreader Bar
The EVA-EG2 extended grid is also available. Arrays taller than four modules will probably require the ex-
tended grid, whose side arms are 11 inches longer to the rear. Three- to four-module arrays which require
more down angle than what is available with a standard grid will also require the extended grid. Figure 17
shows the extended grid.
