Kadee offers couplers designed to meet NMRA standards, making them suitable for many HO scale applications when installed correctly. Always consult mounting and height guidelines for best results.

What is the difference between standard and whisker couplers?

Whisker couplers use built-in centering whiskers instead of a separate centering spring, which can simplify installation and reduce small parts during assembly.
