Ultimate Physical Defense: New Fork Barrier Container Seals
When standard locking mechanisms are not enough to deter organized cargo crime, the NEW FORK SEAL® provides an impenetrable layer of physical security. Recognized as one of the most robust barrier container seals on the market, it is the result of LeghornGroup’s many years of experience in developing anti-loss, theft, and tampering systems for high-risk cargo transportation. Fully compliant with strict ISO 17712:2013 High Security Seal standards, it is engineered to protect valuable freight against the serious threats of illegal immigration, terrorism attempts, and aggressive break-ins.
Heavy-Duty Galvanized Steel Construction
The core strength of these barrier container seals lies in their massive metal framework. Manufactured from premium galvanized steel, the New Fork Seal physically locks the central keeper bars of the shipping container doors together. Even if the hinges or standard latches are attacked, the container doors cannot be swung open. To secure the barrier, it utilizes our high-security Neptune Seal bolt lock, ensuring that the system can only be removed at the destination using heavy-duty industrial cutting tools.
