A lockbox is a steel enclosure that is welded onto the doors of a shipping container to provide additional security for the lock. The lockbox covers the padlock and prevents it from being cut or tampered with using bolt cutters or other tools.
To use a lockbox, simply attach the padlock to the latch on the container doors and then insert the lock into the lockbox. Close the lockbox and secure the padlock. This ensures that the padlock is protected and cannot be easily removed by unauthorized individuals.
