Enjoy automatic trailer coupling with the unique auto-locking mechanism of this SecureLatch pintle hitch. Just back up to the trailer tongue -- the integrated striker plate helps stop and center the lunette ring. Drop the ring onto the ball and hook, and the SecureLatch mechanism automatically engages the primary lock. Just insert the secondary safety pin and youre ready to tow. This unique pintle ball hitch also has a cupped design to hold the lunette eyelet more tightly and deter chucking noises. This ball and pintle combo is rated for 20,000 pounds gross trailer weight, 10,000 pounds ball capacity and is constructed from austempered cast iron for superior strength and wear resistance. It has a standard 2-inch ball and fits 2-1/2-inch or 3-inch lunette rings. NOTE: SecureLatch slotted pintle mount required for installation (pintle mount and bolts sold separately).
