7.9 Hooks
7.9.1 General
Check hooks for deformation or cracks. Hooks must be replaced if throat opening has increased by more
than 15%, or if throat opening has more than 10-degree twist from plane of straight hook.

Due to many types and sizes of hooks that can be furnished and/or specified by the user / owner, it is
recommended that user / owner measure the actual throat opening of hook as originally furnished. See
Figure 17. Record the throat dimension on above sketch. Retain as a permanent record. This record can
then be used for determining when hook must be replaced due to deformation or excessive throat opening.
