The Ring RCT1410 is a towing mirror that gives you a wider field of vision, so you can see behind your vehicle. With these easy to use towing mirrors, you'll be able to see at least 4m either side of your caravan or trailer, which is a legal requirement. Easy to install, with no tools necessary, and able to fit most vehicles, the adjustable straps allow them to be fitted securely to your wing mirrors. Vibration resistant.
