The #156 "Scale" Long Coupler will work anywhere a #26, #36, & #146 Coupler will work.

The #156 "Scale" All Metal Self-Centering WHISKER® Coupler features a "Scale" Metal Coupler (a smaller head coupler which is more to scale and is patterned after the type 'E" couplers) & Metal WHISKER® Centering Spring, insulated Draft Gear Box and Lid. The #156 Coupler may be mounted in Manufacturers cast-on coupler pockets or any of our HO-Scale draft gear boxes (except #233 30-series gear box). The coupler will couple and uncouple with other Kadee® HO and HOn3 couplers. The coupler has the same shank length as the #26, 36 or 46 coupler which will allow the modeler to remove the existing #26, 36 or 46 coupler and replace with the new smaller coupler. The #156 coupler is made of the same metal as the #46 for strength and rigidity.
