* These values are nominal since the dimension is not controlled to a tolerance. The "g1"
dimension should be measured when the hook is new - this becomes a reference measurement.
Subsequent measurements are compared to this reference to make determinations about hook
deformation/stretch. See Section 5.7, “Hooks - Stretch”.
