How to measure your coupler
Drawing of a bracket with the pin diameter (1), the pin centre distance (2) and the ear width (3) marked

Not sure which system it is? Three measurements tell us which bracket you need.

  1. Measure the diameter of both pins.
  2. Measure the distance between the pin centres.
  3. Measure the width between the inside faces of the ears.

If the coupler has a make or type printed on it, send that too.
