This is a set of fifty large dummy knuckle couplings designed to fit into NEM sockets on British outline wagons.
These are large which means they are 2mm taller than a standard Kadee knuckle coupler to allow for different NEM pocket hights.
Please refer to my website for the different types of couplings available.
These couplings are only printable in the Black Versatile Plastic material.
