Imagine a ball mount that requires no tools and no trailer ball torqueing for installation. In fact, it requires no trailer ball installation at all. Simply insert the shank into your trailer hitch receiver, secure it with a pin and clip and you are ready to tow. Now imagine that same ball mount with a sleek, modern look in a popular European design.

Designed to replace a common, old-style ball mount, each CURT Euro Mount is faster and easier to install with its permanently installed trailer ball. With the tow ball permanently fixed to the shank, the ball can never come loose and can never be stolen. The unique European design was created for the U.S. market, combining form, function and aesthetics.


  • Precision robotic welding for superior strength and fit
  • Bonderite® and powder coating provides superior rust, chip and UV protection
  • Industry-leading safety and performance testing
  • Back end of receiver is open for easy cleaning
