ISO 17712 Certified 3.5x250mm Cable Locks: High Security Container Seals
For international exporters and domestic logistics managers who require both flexibility and strict customs compliance, the CABLESEAL with a 3.5 mm cable diameter offers the perfect trade-off between a maximum security degree and versatility of usage. Fully approved and compliant with the stringent requirements imposed by ISO 17712:2013 as a High Security Seal, these adjustable container seals are designed to protect high-value cargos during complex shipping routes and intermodal freight operations.
Anti-Corrosion Anodised Body & Tamper-Evident Steel Cable
The 3.5×250 mm CABLESEAL features a robust body completely made in anodised aluminium, from which a heavy-duty steel cable extends. Anodising is a non-spontaneous electrochemical process by which a protective oxide layer forms on the surface of the treated metal, effectively protecting it from corrosion and severe marine weather. To lock these container seals, simply insert the opposite end of the steel cable into the hole and pull it to the maximum possible extent. Once locked, there will be no way to open the seal unless by breaking it with good shears, ensuring irrefutable tamper evidence at the destination port.
