The NO.5® Kadee® Magne-Matic® Coupler features a Metal Coupler, #634 Centering Spring.
It is not recommended to use a metal coupler directly on a metal surface or in a metal draft gear box to avoid the possible electrical crossover or shorting that may cause damage. Use an insulated draft gear box or use the very strong plactic isolated #28 Coupler which has the same mounting dimensions as the NO.5® Coupler.
Contains ten pair of NO.5® Metal Universal Kadee® Couplers with phosphor bronze metal Centering Springs.
NOTE: Does not include Draft Gear Boxes or Lids.
