Hey John, thanks for reaching out!
I tried looking up that coupler online and there was a plethora of results that popped up so I can't be confident that I found the right one.
If you're looking for a coupler that easily pops onto the hitch ball then I recommend checking out the Demco Cast Head Coupler # DM37ZR which has the eZ-Latch system on it. This coupler latches to the hitch ball when you drop the coupler onto your ball mount setup, which simplifies hooking up your trailer.
Attached is a review video for you to check out. Be sure to tell me what you think!
