The 742RR Bolt Seal is C-TPAT compliant and meets or exceeds ISO 17712 requirements as a High Security Seal.
The Unolok Bolt Seal is made of a solid steel pin encased in polypropylene and barrel encapsulates the ink jetted seal imprint and numbering to prevent tampering. It also features duel numbering on the pin and the barrel to prevent substitution or replacement.

130° limited barrel/pin rotation prevents tampering by spinning the pin or barrel, yet allows the seal to be rotated slightly in order to better read the imprint. The pin and barrel are individually bagged for easy record keeping and distribution to drivers.

This C-TPAT bolt seal is most commonly used on shipping and intermodal containers and widely used for ground transportation.

Pull apart strength is 4,400 lbs
