Accucraft Ride-On - 1.5/1.6" Scale Steel Coupler.  An improved version of the 1.5" coupler design.  This all new patter features  a taller knuckle head, 1 3/4 inches overall, This is to reduce the premature uncoupling of cars due to the couplers sliding out from one another and maintains a closer to prototype look!  The coupler also has an upper trip pin for adding cut levers and or easier manual uncoupling from the top of the coupler.  Replacement Knuckle and trip pin are avalable separately to upgrade older couplers from Train Mountain and RMI coupler and other base on this design.
