Yellow Balls to Align Trailer Hitch - Reese SoloHitch

The SoloHitch from Reese Towpower is a convenient way for one person to align their trailer. 2 high visibility yellow balls sit atop telescoping rods. The rods have magnetic bases, so just set one on your tow ball mount and one on your trailer coupler. Set and mark the heights with your trailer connected. When you want to re-hitch, extend the rods to the marked positions and set them in place. Just back up your vehicle until the yellow balls line up and meet - you'll get perfect alignment every time! Rods extend up to 42" high, so you can see the balls in your rear view mirror. Manufacturer's part number: 7012900
