How to Determine Correct Hitch Ball Size for a Fulton Coupler

The Fulton Fas-Lok Coupler # F222000301 does have the same 22 200 SAE Class 2 numbers that you referenced but that has to do with the testing as opposed to the hitch ball size. If you check out the picture that I attached you can see that the handle itself has 2" Ball engrave on it. Your coupler should have this on the handle or on top of the coupler part that sits directly on top of the hitch ball.

If you still can't find it then you should be able to go to your local home improvement store and try different hitch ball sizes with the coupler or you can try using an adjustable ball mount like the part # 3371802225 or # BWTS10047B. Both of these come with the 3 basic hitch ball sizes of 1-7/8", 2", and 2-5/16". I like to recommend these types of ball mounts for people with pickups since trucks can be used for a variety of towing applications.

You should be able to find the VIN of your trailer either on a sticker or stamped on the frame near the tongue. It should also be on the bill of sale if you can't find it on the tongue.
