An easy to install device which makes hitching your caravan or trailer a breeze. The side arms ‘guide’ the trailer hitch towards the tow ball, thus preventing damage to the tow vehicle. Made from double dipped, zinc plated steel. Extensive research has been conducted to make COUPLE-MATE suitable for use with standard coupling devices up to 3-3/8 inches or 86mm flanged width, measured at the rear of the ball socket.
