Cable seals are high-performance tamper-evident locking devices constructed from strong steel cable and aluminum alloy locking heads. Their one-time locking mechanism ensures that once applied, the seal cannot be reopened or reused, providing reliable protection against tampering and theft. They are widely used in logistics, transportation, utilities, and industrial security applications.
Our products meet international standards including ISO 17712:2014, C-TPAT, ISO 9001, and RoHS compliance, ensuring they are recognized by global customs authorities and logistics providers. This guarantees smooth cargo clearance and secure supply chain operations across international markets.
Featuring a simple self-locking design, cable seals can be installed quickly without tools. The cable is inserted into the locking body, where the internal mechanism locks automatically. This user-friendly design allows efficient one-hand operation, improving productivity in high-volume environments. Removal requires cutting tools and leaves visible damage.
These seals are widely used for container shipping, rail freight, road transport, fuel tanker sealing, air cargo security, courier services, banking, and utility systems. Customization options include cable specifications, locking structures, and marking details.
