What Is a Cable Seal?

A Cable Seal is a tamper-evident security seal made from a steel cable combined with a locking body. Once locked, the cable cannot be removed without cutting or breaking, providing clear evidence of unauthorized access.

Cable seals are widely used to secure shipping containers, trucks, trailers, railcars, warehouses, valves, and high-value cargo. They offer higher strength than plastic seals and greater flexibility than bolt seals, making them suitable for a wide range of security applications.

Many cable seals are designed to comply with ISO 17712 standards, especially for customs and international logistics. They are typically single-use and can be customized with serial numbers, barcodes, or laser-engraved logos for tracking and traceability.
