The HOC-LOC™ Truck, Trailer and Chassis Brake Lock, along with our Interior Trailer Door Lock, and Container Door Lock, provide the best cargo security system on the market today.

The HOC-LOC™ Truck or Trailer Security Products can be installed independently, or in combination with other products and components.

● With HOC-LOC™ protecting your fleet, rest assured your trailers will remain where you left them!
● HOC-LOC™ engages automatically every time the parking brake is set.
● Now you can have security with or without a tractor attached to the trailer and, as you know, 
   unattached means uninsured.
● Can be linked to satellite tracking systems for remote configuration and operation.
● Hazardous materials security for items such as fuels, chemicals, and pharmaceuticals.
● Qualifies for many insurance company discounts.
