Fulton's Wedge-Latch™ Cast Head Couplers feature our new replaceable ball clamp assembly. This new mechanism improves latching ease and allows users to keep the coupler in service for the life of a trailer. Why cut off a coupler if all you need to do is replace some hardware. Once secured on the ball, the Wedge-Latch™ (patent pending) is designed to increase clamping force as the ball attempts to leave the pocket. This provides added coupling security for your precious cargo. A cast shield protects the latch handle assembly from impact damage, while the heat-treated clamp provides years of hassle free service. Available in prime paint finish. Available in 2" & 2-5/16" ball size rated for Class III and IV in round jack applications. Meets and exceeds S.A.E. J684
