Kato 20-010 N Scale Unitrack 186mm (7 5/16") Straight Track pack of 4

The UniJoiner is the basis for Kato’s UNITRACK worry-free design. As a Removable connector slip, the UnJoiner can be replaced in the event that a piece breaks (unlike other snap tracks there the entire section of track will have to be replaced), and can be easily swapped out for wired UniJoiners or insulated UniJoiners for more advanced layout wiring techiques
