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.

To check coupler height, set the coupler into the talgo truck pocket and hold it level as possible and check the coupler height with a 205 or newer 206 HO coupler height gauge. |

NOTE: So it is important to check coupler height and make sure it is correct “before” you insert the talgo truck adaptor, because it’s almost impossible to remove without breaking something. |
