A shackle must be marked with the rated load, re-inspected due date, and the date manufacture.

• A. True
• B. False
• C. Not required
• D. Only for certain types

Answer: (B)

Knowing what information is required on rigging hardware markings helps you use the right tool for the job and trace it if needed. For shackles, the essential marking is the working load limit (rated load) along with the device’s identity (size and manufacturer). The date of manufacture and a re-inspection due date are not typically stamped on the shackle itself; those dates are managed through inspection records or tags attached to the rigging assembly, not etched into the shackle. So, the statement that a shackle must be marked with the rated load, re-inspected due date, and the date of manufacture is not correct.
