Hello Carolyn, thanks for reaching out. The square hole you are referring to is known as the hitch receiver. What goes into this is called a ball mount, or drawbar such as part # e67DR. The ball then attaches to the ball mount. The # e67DR I mentioned comes with a 2" ball.

Do you know what size of ball your trailer requires?
