Flexsecure FS50 High Security 5mm Cable Seal 

The Flexsecure 50 is our strongest and most robust high security 5mm cable seal,  for high-value container movements. Featuring a 5mm diameter cable the Flexsecure 50 is suitable for the toughest of applications. The seal can withstand over one tonne of tensile load. It is classified as a High-Security seal as per the ISO 7712:2013 testing standards and is C-TPAT compliant. The Flexsecure 5mm cable seal can be used to seal cargo being transported through customs internationally, including between the UK and EU after Brexit.

The non-preform cable frays wildly when cut and is galvanized for corrosion protection. The patent pending locking mechanism inside the anodized aluminium housing makes sure your goods are safe in transit.
