The next evolution of model train couplers starts and ends with the Kadee® Whisker® series of couplers. The scale size and detail of the 58 coupler has long been popular with model railroaders, so we knew we had to offer a Whisker® version. Behold the 158 – a scale sized coupler with smaller head and knuckle for a more prototypical look. Often referred to as the “Whisker® version of the 58”, the 158 features an even longer-lasting and more reliable design. No more fumbling with centering springs. No more multi-piece assemblies. The 158 Whisker® coupler is a true drop-in coupler. Use Kadee® Whisker® couplers in your next model and enjoy the most reliable and smooth coupling experience you’ve ever had. Always made right here in the USA with legendary Made In America quality.
The 178 is a special product. It features 158 Scale couplers with special scale-sized gearboxes. This unique combination results in one of the most prototypical looking coupler setups in model railroading.

- (2) Pair 158 “Scale” Whisker® Metal Couplers – Medium Centerset Shank
- (2) Pair 178 “Scale” Snap-Together Gearboxes & Lids

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.
