Cable seals
Security seals with body and safety elements made by metal. Attachments are made of metal cables which provide a variable length closing and sealing solution. Cable seals allow for more versatile application, as they have variable length of the locking mechanism limited only by the cable length. Typical applications for cable seals include sealing trucks and railway cars transporting valuable commodities. An internal locking mechanism prevents the cable from being retracted. Most cable seals are classified as security or high security level as to ISO 17712. All ISO 17712 compliant security seals are numbered on both seal body and head, to prevent substitution of either part. This is usually done using laser marking, which cannot be rubbed off.
For the attachment of trucks usually use the seals with balls. They consist of a metal tape with the pierced hole, attached to the section of the casing. When the tape is bent and threaded through the hole, the ball inside the hull section locked it in place. Most type of ball seals belong only to the indicative level of ISO 17712.
