Use the HO-Scale Coupler Conversions to lookup our suggested starting coupler* for the particular model. (Our conversions typically requiring the least modification to a model utilizing our newest couplers even though other couplers also work for the model).


Once you have lookup our suggested starting coupler you can use our HO-Scale Coupler Conversions (How -To instructions and diagrams) to help you with the couplers installation process. Always check the coupler heights with either our #205 or newer #206 Coupler Height Gauge.


Note: If the model came with Factory Knuckle Couplers it will not be listed on the HO-Scale Coupler Conversions under manufacturer there is a generic conversion for Factory Knuckle Couplers on the top of the HO-Scale Coupler Conversions.

*Our conversion’s based on only one model from a production run, there may be inconsistencies in a model’s production run that require a different coupler or model modifications to achieve the proper coupler height for coupler function.
