RadioSecure SLJ cable system


The RadioSecure™ SLJ e-seal system leverages the ability of the SLM to detect when its cable is removed or cut.

This allows long cables to be used to seal tautliners or flatbed trailers. Cables are threaded through buckles to reduce the number of seals required to secure tarpauling curtains. To make longer lengths less cumbersome, SLJ junction boxes can be employed as many times as required along the length of the truck, dividing a long run into multiple shorter cables

If any section of the cable is disconnected or cut, the SLM will send an unseal event to the servers for logging and immediate alert for attention.
