Micro-Trains 00102300 - True-Scale Short Shank Coupler (Black) (1300) - 2 pair

This easy-to-assemble and install body mount coupler consists of a draft gear box, lid, knuckle, lip shank and a separate plug-in air hose.  There are no springs.  They are uncoupled manually using a sharp toothpick or a needle and can be joined by simply pushing the cars together. These couplers are to scale so they will not couple with existing larger N scale couplers.  For those who have Magne-Matic or other coupler systems, you can use a conversion car, which comes with a Magne-Matic installed on one end and a True-Scale coupler on the other.
