The TOTALPACK® High Security Truck Steel Seals Pin Locks are designed for maximum security in high-risk applications such as shipping containers, trucks, trailers, and railcars. Featuring an anti-spin locking mechanism, these seals prevent tampering by spinning the pin or barrel. The steel bolt and plastic-coated steel locking chamber are tamper-evident, with a high-impact plastic cover on the locking pin that shows any signs of tampering. Both the bolt and barrel are laser-etched with matching serial numbers for added traceability. Suitable for ISO containers and high-value shipments, this high-security bolt seal ensures integrity and safety throughout transit.
