The Grand Aero 4 Mirror offers all the benefits of the Aero 3 Mirror, plus the maximum view possible, combined with very high stability. The Grand Aero 4 Mirror enables you to see the top and bottom of your caravan so you can avoid hazards, such as low trees branches, signposts sticking out etc. As you would expect from Milenco, this is a very high-quality product, manufactured with the best materials available. The mirror screws are high-grade stainless steel and turn in brass inserts that will never corrode. The mirror glass is chrome safety glass, which will offer extremely long life and will not discolour after a few years. The unique and new clamping system (patented plus international patents pending) now on the Grand Aero 4 Mirror is further improved to have much greater grip and improved fitment. The clamps will now fit on vehicles with compound tapered flanges on the vehicle mirror housing, such as on 2016 Land Rovers and Jaguar's. These new clamps offer an outstanding and versatile system, which is engineered to fit all current (post 1995 - 2021) cars, 4x4's and vans. This system has easy to use thumb wheels on tilting axis, which enable the clamps to 'shape' to the contours of the vehicles mirror, allowing totally versatile fitting. Another innovation of this design is the upgraded gripper system, so you do not lose the grip pads. This design also does away with unreliable straps that transfer vibration. The Grand Aero 4 Mirror head design (Registered Design) utilises airflow around your car to stabilise and balance the mirror head at speed. This mirror has been extensively tested at speeds up to 220kph (137mph), to ensure that you get the best vision possible. This design also offers superior performance in high winds and the effect of passing large commercial vehicles has been minimised. The Milenco Aero 4 Grand is available in both Flat and Convex mirror styles.
