HO Knuckle Spring Lower Shelf Coupler with Pin (MCH31)

HO Knuckle Spring Lower Shelf Coupler with Pin is a scale-sized, spring-loaded knuckle coupler for HO-scale freight cars. Its lower-shelf design yields a realistic silhouette, and at roughly three-quarters the size of standard couplers, it preserves proportional accuracy on contemporary rolling stock.

They are built to AAR standard E safety coupler specs, making them compatible with a wide range of HO freight cars. The lower shelf design reflects equipment commonly seen on post-1980 freight cars, enhancing the look of yards and sidings. This version does not include a magnetic uncoupling pin.
