The Dual-view Clip-On Towing Mirror provides better towing vision than any towing mirror out there! This innovative product features two fully adjustable mirror surfaces that allow you to fully customize your viewing area. The Dual-view Clip-on's large, flat mirror surface gives an accurate perspective of what is behind you, while the smaller convex surface acts as a built-in spot mirror for increased safety while driving, passing or changing lanes. Plus the fully enclosed mirror head design not only reduces wind vibration, but also ensures that the Dual-View's adjustable mirror surfaces stay right where you put them. This universal mirror features two adjustable arms and rubber straps that will not obstruct your existing mirror. Fits most 7" to 10" mirrors. Expand your Horizons.
