*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”.
