text: External Loads
  CAUTION
  Each sling set has four legs. Each leg has a rated capacity of
  one-quarter of the total capacity of the set. On some loads, you will
  use up to six legs. However, remember that adding two legs does not
  increase the rated capacity of the entire set.
  5-45. The nylon rope assembly for each set has an interwoven eye located at each end. A polyurethane
  fitting covers the eye to protect the leg from abrasion and ultraviolet radiation (Figure 5-9). Each
  double-braided rope connects to a grabhook assembly. Figure 5-10, Figure 5-11, and Figure 5-12 show a
  coupling link, sling leg-numbering sequence, and a grabhook, respectively. Though the grabhooks for the
  two sets look alike, you cannot interchange them because they have different ratings.
  5-46. FM 10-450-3 and TM 10-1670-295-23&P discuss how to inspect the rope sling sets.
  FM 10-450-3 also provides sling-conversion tables.
  5-47. Secure the cross pin on each apex fitting with a 3/8-inch bolt, a castellated nut, and a cotter pin.
