6.53 Symmetry for Horizontal Clusters using HRK Kits
The cluster’s center of gravity is centered under the two suspension points in a two-over-two cluster (see
Figure 33a) or between the suspension points in a three-over-three cluster (see Figure 33b).
Both the cluster’s weight and center of gravity must be symmetrical about the cluster’s center line. For
individual enclosure weights and centers of gravity, refer to section 1.
