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#28 Magne-Matic® Plastic Coupler may be mounted with the included #213 or #232 Gearbox or with most other manufacturers cast-on coupler pockets.
The #28 Coupler is the plastic equivalent to the NO.5® Metal Coupler.
It is not recommended to use a metal coupler directly on a metal surface or in a metal draft gearbox to avoid possible electrical crossover and shorting that may cause damage.
Refer to our helpful Coupler Conversion Charts to determine the appropriate coupler to use on your model.
