#5 HO Scale (No.5®) Universal Metal Couplers with Gearboxes - Medium (9/32") Centerset Shank
No.5® Metal Couplers - Medium Centerset Shank
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.

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.
Refer to our helpful Coupler Conversion Charts to determine the appropriate coupler to use on your model.

*Note: Some manufacturers now produce models with non-industry standard coupler pockets (molded-on gearbox). These shallower coupler pockets may require slight modification to the gearbox or coupler to function properly. If the model has a shallow molded-on gearbox, a #148 Whisker® coupler should be used instead of a No.5® coupler. The top of the #148 Whisker® coupler shank may be filed thinner to fit the shallower cast-on coupler pockets.
