Here is one expert's view after initial testing: "the shackle can't be cut, the bottom is secured with a
steel plate so drill attacks are resisted, the lock cylinder itself can't be pulled out and chiseling
won't work because of countersunk rivets.
"  In high security situations, is is an efficient option.  
Comes with warning flag, carry handle and two keys per lock.
Keyed different options as well.
Our king pin locks are a solid solution for trailer security and logistics control.  They secure the king pin of semi-tractor trailers and prevent trailer hookups when parked or in a drop
location.  The kingpin locks work on all 5th wheel type pins, including semi's and travel trailer fifth wheels alike (RV trailers with fifth wheel hitches use the same basic pin as
semi-trailers). Our kingpin locks are casted from ductile steel for maximum strength and resistance.

These anti-theft devices stand out with brightly colored powder coating, allowing a driver to see that a king pinlock is attached before any hitching occurs.  Our king pin locks
prevent unauthorized hookups to fifth-wheel trailers and give you the trailer control and security needed in today's demanding and changing environments. Look to Carrier Security
for all of your trailer security and trailer control needs.

Trailer theft is on the rise!  Protect your trailers with our king pin locks!  Distribution Centers are the No. 1 location for stolen cargo.  Truck Stops rank high but not as high as the DC's
and terminal lots themselves.  Even terminal areas considered "secure" are not enough to stop protect the trailers themselves - let us help you reduce your risks.  Theft of lower
valued goods has increased dramatically in recent years.  Monthly incidents the most ever recorded in this past year alone.

Quick tip: Slip a plastic sack over the king pin before installing the king pin lock, this will help stop grease sticking to the kingpin lock after each use.
