Product Information
The EnaBolt 5B is a high-security bolt seal engineered to provide maximum protection for cargo and containers. Compliant with ISO/PAS 17712:2013 and C-TPAT standards, this seal is ideal for global shipping and logistics applications where tamper evidence and regulatory compliance are paramount. Its innovative anti-spin design ensures that attempts to rotate or tamper with the seal using high-speed techniques are easily detectable, maintaining the integrity of secured shipments throughout transit.
Manufactured using a one-time injection moulding process, the EnaBolt 5B provides enhanced tamper-evident properties, making it clear if any unauthorized access has been attempted. The seal’s large flag allows for clear laser-printed information, including serial numbers, barcodes, or custom company markings, providing traceability and simplifying cargo management. The dual-color injection design not only improves visual identification but also adds another layer of security against counterfeiting.
Designed for efficiency and reliability, the EnaBolt 5B is produced through automated processes to ensure consistent quality and uniformity across batches. Its anti-rotation function and robust construction make it highly durable, capable of withstanding harsh handling and environmental conditions. This seal is specifically designed to secure intermodal containers worldwide, offering peace of mind to shippers, logistics providers, and customs authorities. Removal requires bolt cutters, ensuring that once applied, the seal remains a reliable deterrent against tampering.
