What Lock Will Work for a Gooseneck Trailer

Expert Reply:

In order to choose the correct lock for your trailer, you will need to measure the outside diameter of the coupler and also the outside diameter of the lip at the bottom of the coupler. From there, I have linked the page with all of the gooseneck locks available.

If you have the manufacturer and part number of the coupler, I can be more specific with a recommendation.
