Ferrolock Anti Spin

A high security bolt security seal for containers, with a pull apart strength of 2 tonnes. For additional security the 7 digit sequential numbering is laser marked onto both the bolt and bush.

This Anti-Spin version of the Ferrolock bolt seal provides an extra level of security against a particular method of tampering, spinning, which is a process using a drill to defeat the bolt seal.
