Metal Band Seals – Model Name MBS-8001 ($0.15 per unit)

The international standard that establishes uniform procedures for the classification, acceptance, and withdrawal of mechanical freight container seals. It provides a single source of information on mechanical seals which are acceptable for securing containers in international commerce.

The highest tier of the ISO 17712 standard. To be “H-Class,” a seal must undergo rigorous physical testing, including tensile (pulling), shear (cutting), bending, and impact tests. Both Joeguard Cable Seals and our Heavy-Duty Bar Seals are engineered to meet this standard.

The maximum amount of pulling force a seal can withstand before the locking mechanism or the material itself fails. For Joeguard seals, this is typically measured in kilonewtons (kN) or pounds-force (lbf). High tensile strength is what prevents manual removal by thieves.

Unlike “tamper-resistant,” a tamper-evident seal is designed specifically to show permanent, visible proof if a breach has been attempted. This includes features like “splayed” cable ends that cannot be re-inserted or laser markings that discolor when tampered with.

The process of applying a protective zinc coating to steel to prevent rusting. This is critical for cable seals (like Joeguard) used in maritime environments where salt air and high humidity would otherwise corrode the locking mechanism within days.

The chronological documentation or paper trail that records the sequence of custody, control, transfer, and analysis of a shipment. High-quality serial numbering on seals is the cornerstone of a digital chain of custody.
