A basic three-over-three cluster is shown in Figure 23.

Main suspension lines and pull backs must be tied to the tie plates.

Note that the HRK kits are designed to make weight-symmetrical clus- ters, i.e., those whose left-to-right center of gravity is in the center of the cluster.

The following components are needed to achieve this cluster:

1.Four HRK-2 horizontal rigging kits for EVF to EVF subwoofer/EVH.

2.User-supplied hardware to link the upper cluster to the lower cluster.
