This industry leading coupler features plastic standard coupler with metal knuckle, and #634 standard centering spring and comes complete with insulated draft gearbox and lid. The #21 Magne-Matic® Plastic Coupler may be mounted with the included #213 or #232 Gearbox or with most other manufacturers cast-on coupler pockets.
