The next evolution of model train couplers starts and ends with the Kadee® Whisker® series of couplers. When we set out to improve upon the venerable No.5® we knew it had to be just as game-changing as the original. We took everything you loved about the No.5® and improved upon it. No more fumbling with centering springs. No more multi-piece assemblies. The Whisker® series of couplers 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 #147 is interchangeable with the #27 and most manufacturer's Medium Underset OEM knuckle couplers. For a #37 equivalent use the #147 in a #252 Gearbox.

Package Includes:

• (2) Pair #147 Whisker® Metal Couplers - Medium Underset Shank
• (2) Pair #242 Snap-Together Gearboxes & Lids
• (2) Spare #622 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 #27 coupler.
