The HOLLAND EH-3050 features 30,000- (13,610 kg) or 50,000-pound (22,680 kg) drawbar pull rating based on mounting fastener size. All cast steel construction incorporates an upper pin guard to protect the pin from impact damage. Large 2.125-inch (54 mm) diameter pin reduces "slop" and wear resistance is enhanced by the increased surface area and heat-treating for hardness. Handle can be changed between fold-down and rigid-up settings. The U.S. Air Force has been field testing this coupler over the past year with great success. A new E-Hitch design launching in 2014 has already been specified by several major airlines.
