To get the most out of your HO Scale setup, you've got to have properly functioning couplers. Whether you model one manufacturer or mix-and-match brands, Kadee® has the info you need. Use our handy HO conversion charts to find the perfect Kadee® couplers to keep your layout running smoothly and reliably. Click on a manufacturer below to find the perfect coupler for your car or locomotive.

Newer models that have factory-installed clone knuckle couplers are easily converted by using our standard head #148 or "scale" head #158 Whisker® Couplers. Always check the coupler heights with either our #205 or newer #206 Coupler Height Gauge.
