Gooseneck Hook-Up HelperThe Hook Up Helper allows drivers to line up the gooseneck ball for an easy, first try connection. The highly visible yellow tube is made of extruded rubberized plastic with a wide lengthwise slit and fits over the ball in the bed of the truck. The driver can easily see the marker through the rear view mirror to help align the gooseneck hitch. Once the hitch makes contact with the ball cover, the cover will pop off and will allow a perfect connection
