Designed to replace old metal couplers on 4 axle passenger cars from Schicht, Piko and others with a standard NEM socket. Allows for use of close couplers for prototypical distances between cars. Reuses stock mounting points and existing spring clip.
The length of the adapter is set to use on cars with gangway connectors that stick out past the buffers. Some adjustment is possible by bending the mounting pin back or forth, in case the gangways still hit on sharp turns.
For cars without gangways beyond the buffers use the medium adapter:
For 2 axle and freight cars try the short adapter:
