The one that started it all; the original No.5®. These industry leading couplers feature an all metal construction, standard centering springs, and come complete with insulated draft gearboxes and lids. This is the perfect upgrade for the weak and drooping couplers that come on most factory rolling stock and locomotives. Others have tried to copy the robust design of the No.5® but nothing comes close to the real thing. Our classic 5 couplers are manufactured to the strictest tolerances to ensure reliable operation for decades. And they’re still made right here in the USA with legendary Made In America quality.
The No.5® is interchangeable with the 28, 58, 118, 119, 148, 158, and most manufacturer’s Medium Centerset OEM knuckle couplers.

(2) Pair No.5® Metal Couplers – Medium Centerset Shank
(2) Pair 634 Centering Spring NO.5® Style

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. For insulated couplers use28 coupler.
