HO Type F Short "Dummy" Coupler

This is the Short version of the Type F dummy coupler and is compatible to "Sergent Engineering" HO scale couplers and can be coupled and uncoupled with any sergent coupler type. It can also be manually coupled to a Type E dummy coupler but not another Type F due to the Tight Lock features. This coupler is .040" (1mm) shorter than the Standard Type E coupler
The Type F is typically used on unit trains.
