Align your hitch with the trailer's coupler as you sit in the driver's seat The magnetic trailer alignment kit includes two separate telescoping rods that you magnetically attach to your vehicle's hitch and the trailer's coupler. Then simply raise the bright yellow markers to a height where you can see both of them from your driver's seat, then get in and drive. When you've got the two markers aligned, you're in position to easily hook them up. The rods are chrome-plated to resist rust.
