Trailer coupler to ball security/lock device.
 

I am looking for a product that bolts on when you are installing your ball to the drawbar. It has two sleeves on either side of the ball, and allows a drop in bar to come down over the top of your trailer hitch coupler when you latch down your trailer coupler onto the ball. It does not normally touch, but it is there about an inch above as an extra security measure. I can't find this product anywhere, but I know it exists, and don't know a name. Little help?

Thanks in advance.
