N Scale permanently fixed coupling bars or drawbars for Rapido style couplings. These can be used to keep consisted locos or unit trains permanently coupled.
This set has 6x 6mm (0.236") long couplers.
(The length is from inside to inside).
These have been designed for printing in black Versatile Plastic (formally BS&F) or Fine Detail Plastic (formally FUD).
If printed in the Fine Detail Plastic material they will require cleaning before painting. I recommend washing with warm soapy water then soaking in 'Goo Gone' or similar product for about 24 hours. Then rinsing off with warm water and allowing to dry.
