In response to the growing use of overseas (intermodal) shipping containers by the U.S. trucking industry, Rite-Hite has introduced the RHR-4000 Dok-Lok vehicle restraint. The RHR-4000 rotating hook restraint adds another layer of safety by securing overseas container chassis, which can have a plate or obstruction above the rear impact guard, while maintaining its exclusive hook design that provides the largest wrap over rear impact guards in the industry. The exclusive RHR-4000 also offers a water-and dust-resistant IP66 rated motor and a longer lasting, corrosive resistant finish that meets the ASTM B117 testing standard. 

All Rite-Hite restraints come standard with the Rite-Vu Light Communication System, including Corner Vu (which provides immediate Dok-Lok status-at-a-glance to the forklift driver before entering the trailer) and Leveler-Vu (which confirms Dok-Lok status to the forklift driver while inside the trailer).
