The suspended column must be perpendicular (plumb) to within ±5 degrees.
If suspending a spreader bar or grid from two points, the angle between those two
suspension lines must not exceed 60° (maximum 30° from plumb each).
Never exceed 760 lb (345 kg) total column weight when using the EVA-CG coupler grid
(discontinued). When flying EVA-1151D modules (discontinued) behind EVA-2082S full-
range modules on the EVA-CG coupler grid, the maximum number of EVA-2082S full-range
modules at the front of the grid is five and the maximum number of EVA-1151D
subwoofer modules (discontinued) at the rear of the grid is three. A bottom pull-up is not
allowed when using the EVA-CG. Flying a single column from the EVA-CG is not allowed.
