The 3.5mm Cable Seals are exceptionally durable. We use them for securing domestic rail freight and the non-preformed cable ensures that if it's cut, it frays instantly, making it impossible to re-seal. Top-tier security.

Frequently Asked Question!
Container seals are heavy-duty, single-use locking mechanisms designed to secure shipping containers during domestic and international transit. They serve two primary purposes: providing a strong physical barrier against theft, and offering clear, tamper-evident proof if unauthorized access occurs. At LeghornGroup, our high-security seals ensure your cargo remains untouched from origin to destination.
ISO 17712:2013 is the highest international standard for mechanical freight security seals. It dictates strict criteria for physical strength (impact, shear, bend, and tensile strength) and tamper evidence. LeghornGroup’s top-tier products, like the Neptune Bolt Seal, are fully ISO 17712:2013 compliant, ensuring seamless customs clearance globally and C-TPAT compliance.
Always secure the seal on the right door of the shipping container, as this is the door that must be opened first. For our bolt seals, simply insert the metal pin through the locking hasp and push it firmly into the locking barrel until you hear a distinct “click.” Once locked, pull firmly on the seal to ensure the anti-spin mechanism is fully engaged.
Every LeghornGroup container seal features a unique, sequential identification number. This number must be recorded exactly on your Bill of Lading (BOL) and shipping manifest. We use advanced laser-marking technology to engrave these numbers—along with optional custom company logos and 2D barcodes—ensuring they cannot be erased, altered, or duplicated.
Because our high-security bolt and barrier seals (like the Block Bar) are built to withstand immense physical force, they cannot be broken by hand. They must be removed at the destination using heavy-duty bolt cutters. In contrast, our tamper-evident cable seals are designed so that the non-preformed galvanized steel wire frays wildly when cut, preventing any attempt to re-thread or re-seal it.
If a container arrives with a broken seal, or if the seal number does not perfectly match the Bill of Lading, do not open the container. Document the discrepancy immediately with photographs, notify your freight forwarder or shipping line, and contact your insurance provider. Note that in some cases, customs authorities may cut a seal for inspection, but they will apply a new official customs seal and document the change.
