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 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. The fully enclosed mirror head design reduces wind vibration, to ensure that the adjustable mirror surfaces stay where you put them. Features two adjustable arms and rubber straps that will not obstruct your existing mirror. Size 7-1/2" W x 5-3/4" H
