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 company says.
