Container door locks, commonly referred to as container locks, are mechanical or electronic devices used to secure the doors of shipping containers. These locks are designed to prevent unauthorized access to the contents of the container during transportation and storage. They come in various types and designs, but their primary function is to lock and seal the container doors, ensuring that only authorized personnel can open and access the cargo inside. Container door locks are an essential component of cargo security, helping to protect goods from theft, tampering, and damage during transit. They are commonly used in the shipping and logistics industry to maintain the integrity and safety of the goods being transported in containers.
