Which lock fits my hitch

Fits every Knott coupling

One lock, every range. There is no model-by-model chart to work through — if your trailer runs a Knott coupling, this fits it.

  • KF
  • KFG
  • KRV
  • KS

Checking your coupling

Knott stamp the model code into the casting itself, usually on the top or the side of the coupling body. It will read something like KFG20 or KS35.

If the code starts with KF, KFG, KRV or KS, it is a Knott coupling and the lock fits.

Not sure what you have?

Send us the code stamped on your coupling, or a photo of it, and we will tell you.
