I wonder if Con-Cor will make their Rigid Jaw couplers in various shank lengths and offset jaws . That would be great for many applications such as cab units , ore cars , pilots , etc . I would love to have these to mess with . And the best part is no slinky with something we want close coupled , which they never mentioned in their ad . Less bulky looking than the Red Caboose ones . Con-Cor could be the one to use , if they made these easily available .
