6.41 Working Load Limits for Eyebolts used with VRK Vertical Rigging Kits
Eyebolts are the most convenient way to suspend vertical clusters. Eyebolts attach to the EVF and EVH
enclosures through the integral M10-1.5 attachment points. Section 5.21 Anatomy of an EVF or EVH Fly-
ing System Using M10 Eyebolts should be reviewed at this time for more information on eyebolt alignment
and positioning on the enclosure. Table 12 shows the WLL per eyebolt with respect to the angle of the
applied load. Figure 29 shows the suspension-point angles that are referenced in the table. It is a good
idea to stay within 30° of the maximum WLL of the eyebolt (straight up position) for main suspension lines.
