C2K Compact Reusable Security Seal

Approximately 35,000 sealings.

The truck seal entry level product - low cost and easy to read, the simple security sealing solution for trailers, trucks, tankers, vans and curtain-sided vehicles that can actively reduce your sealing costs.

It generates a random seal number when the security hasp has been threaded through the vehicle locking handle and secured under the actuator knob. A new random number is generated each time the C2K is reseated.

For trucks, trailers or tankers with side doors, hatches or multiple access points, both Manta and C2K offer the unique facility to hard wire remote sensors in series, generating a single unique load number while removing the need for a separate mechanical seal at each point.
