What is the difference between a king pin lock and a gladhand lock?

King Pin locks

King Pin locks fit over a trailer’s kingpin and prevents an unauthorized tractor from pulling up to your trailer and driving away.

Gladhand locks

Gladhand locks slip over a trailer glad-hands and seals the air lines to prevent an authorized company from moving the trailer.

 

We recommend using both locks to provide an additional level of security against the theft of road and storage trailers.
