5" scale Class 37 screw link coupling. 
 
Modelled from full size engineering drawings, our screw coupling is faithful to the full size in that the screw has both left and right hand working threads. This allows the screw coupling length to be set in a scale configuration depending on the look being achieved.
 
The hinged handle (snaps in to place) and working screw threads ensure the screw coupling sits in a realistic manner once fitted giving the ultimate scale look to your model locomotive.

Ideal for adding ultimate detail to your 5" gauge diesel locomotive.
 
The hook has been sized to locate in to our coupling plate cover slot.
 
Important! This is a non-functional (plastic) scale accessory and should not be used as a functional coupling for any kind of passenger or freight hauling.
