The SMART-HOOK® AR-20K is the premium industry leading automatic vehicle restraint designed to secure virtually all trucks at the loading dock by using a large rotating hook to engage a trailer’s rear impact guard (RIG).
Featuring the NO-PINCH™ Auxiliary Lock System, POWER-SAFE™ Battery Reserve System and patented IMPACT-GUARD™.
The AR-20K offers the most enhanced loading dock safety and performance in the industry.
The patent pending NO-PINCH™ Auxiliary Lock System will not pinch the rear impact guard, providing the highest level of safety in the vehicle restraint industry.
The patented IMPACT-GUARD™ front carriage reinforcement increases front carriage strength by over 10 TIMES competing designs and protects your investment from damage caused by incoming trailers.
The POWER-SAFE™ battery reserve system supplies auto-recharging battery power to the restraint and communication lights for over 24 hours allowing you to stay safe, engaged, and in control at all times.
With maximum mounting force exceeding 100,000 pounds, AR-20K restraints are capable of holding the heaviest trucks while the locking hook secures virtually all rear impact guards in excess of 32,000 pounds of restraining force.
The patented Direct Drive System and Advanced Waterproof Hook Sensor replace moving parts that will fail in competing products.
Eliminating these parts substantially reduces maintenance and downtime resulting in a lower cost of ownership.
NORDOCK® has continued to evolve the SMART-HOOK® vehicle restraints to meet all the changes and challenges in the industry, by offering innovative new options to help maximize safety at your loading dock.
