Anti-Spin High Security Seal,Bar coding can also be applied .The seal is in compliance with ISO 17712:2013 as a High Security Seal and is C-TPAT compliant Security seals can be split into two main groups: single-use and reusable. Single use seals are typically made of plastic or metal, and the used material and production technology is the key to their security level. 

Reusable seals are usually electronic or mechanical rather than just made from plastic, and if purely plastic, only one part is reusable. Electronic and mechanical seals are generally used for the transportation industry, with seal fixed to the back of trucks, trailers and shipping containers. A reusable mechanical or electronic seal can be fitted to the rear or loading doors, extending a cable from itself through fixing points on the doors, and when sealed generating a unique number which is logged. When the door is next opened this number changes, so it provides tamper evidence for the load. 

This bolt is so advanced that unlike other bolt seals it has an anti-spin system which once locked doesn’t allow the bolt to spin and if someone tries to spin the lock it will deliberately crack the outer shell of the bolt to indicate tampering to the seal. is a C-TPAT and ISO 17712 “H” compliant.
