Kadee 58 HO Scale Metal Couplers With Gearboxes Medium (9/32") Centerset Shank

#58 "Scale" Metal Couplers - Medium Centerset Shank While the No.5 was revolutionary, the #58 is evolutionary. We took our legendary No.5 coupler and shrank the size of the head and knuckle to create a coupler that's even more prototypical. 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. #58 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 #58 is interchangeable with the No.5, #28, #118, #119, #148, #158, and most manufacturer's Medium Centerset OEM knuckle couplers. Package Includes: (2) Pair #58 "Scale" Metal Couplers - Medium Centerset Shank (2) Pair #634 Centering Spring NO.5 Style (2) Pair #232 Gearboxes (2) Spare #625 Knuckle Springs 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. Kadee Magne-Matic Couplers and Uncouplers are a complete system for your model railroad layout.
