Hey, Carl.
There isn't one specific lock that would be for that coupler. I tried to find some sort of picture of even a drawing of the coupler to see what style would be best for it but I couldn't find anything out there. What I do know about that coupler is that it takes a 2" ball.
You can get a universal type of lock like the Trimax part # TMX47FR. I personally would go with the InfiniteRule Trailer Coupler Lock Kit part # IR57RR. Main reason is the kit comes with multiple locks that are all use the same key. This will give you options of what lock you want to use or use all the locks at the same time if you wanted.
