6.0  Rigging-Strength Ratings and Safety Factors (cont’)
6.4 VRK Rigging Structural Ratings for Vertical Clusters
The guidelines for simplified vertical structural ratings cover the following information:
1. 
Maximum length of the cluster.
2. 
Maximum weight of the cluster.
3. 
WLL for eyebolts.
4. 
Trim angle.
5. 
Tie points for eyebolts.
6. 
Left-to-right vertical cluster angles.
The majority of vertical clusters will be suspended using a combination of VRK vertical rigging kits and 
factory-supplied eyebolts. For a vertical cluster, select the eyebolt position that results in the highest eye-
bolt strength as shown in Table 12.  Different eyebolt positions are shown in Figure 28.
