The one that started it all; the original No.5®. These industry leading couplers feature an all metal construction and standard centering springs. 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. Package includes(20) Pair No.5® Metal Couplers - Medium Centerset Shank, (20) Pair #634 Centering Spring NO.5® Style, (4) Spare #622 Knuckle Springs **Gearboxes not included**
