The #148 Whisker® Metal Coupler will work anywhere a NO.5® Coupler will work and is a direct replacement for most Bachmann On30 couplers & a direct replacement for most plastic Medium Centerset "clone" couplers.

This industry leading coupler features an all metal coupler head, shank, and Whisker® centering spring and comes complete with and insulated draft gearbox and lid. The #148 Magne-Matic® Whisker® Metal Coupler may be mounted with the included #242 Snap-Together Gearbox or with other manufacturers cast-on coupler pockets.

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. Use the provided insulated gearbox or insulated #28 coupler.
