Product Overview
High-security bolt seals are maximum strength physical barrier locks that protect intermodal ocean freight, shipping containers, rail wagons and cross-border commercial trailers. Unlike lightweight plastic or metal strap seals that only provide basic indication, a premium high-security bolt seal is a heavy-duty physical lock designed to resist extreme physical force and deter opportunistic break-in attempts.
High-security bolt seals are heavy-duty, tamper-evident solutions designed to secure containers, trucks, rail freight, hazardous materials, and high-value cargo across the global supply chain.
