Extend Your Rear-View In Safety & Security: Dual Mirror Pantograph Mount The dual mirror system gives you two separate rear-views. The small, outer mirror measures 110(H) x 40(W)mm and is adjustable up-down and right-left. This enables you to have an image projected to your face from a considerable distance behind you. A larger, second mirror, 115(H) x 125(W)mm enables you to see the lower sides of your car, caravan in relating to nearby traffic, etc. It operates on a pantograph action for safety and security of mounting. Heavy moulded clips and neoprene straps attach to existing rear vision apparatus.
