6.0 Rigging-Strength Ratings and Safety Factors (cont’)
6.32 Suspension-Line Angles
Refer to Table 9 and Figure 25 for specific eyebolt angle and weight limitiations when using all-eyebolt clusters. These limits are not to be exceeded under any circumstances. If a higher safety factor than 8:1 is required, the angle limitations for each eyebolt may actually decrease to a number less than what is shown in Figure 25.
Always make sure that the suspension line is in the plane of the eyebolt, as shown in Figure 17. Readjust the eyebolt during the installation if necessary to maintain this alignment.

The suspended all-eyebolt cluster must be perpendicular (plumb) to within ±5° as shown in Figure 27.
