148 Whisker Cplr #5 Rplcmnt (4 (KAD148)

HO-scale Kadee Magne-Matic Whisker Couplers are replacement units designed for reliable, smooth coupling on model railcars. Each two-pack includes a metal-bodied coupler with a metal Whisker centering spring and an insulated draft gear box with lid, providing a ready-to-install upgrade for HO rolling stock.

These couplers can be mounted in the supplied insulated draft gear box or in standard manufacturer pockets. To prevent electrical issues, do not use a metal coupler directly on metal surfaces or inside metal draft gear boxes; always use the insulated draft gear box included with the set.
