A great spare part for your Milenco Aero 4 towing mirrors! Single replacement clamp that can be used on the Milenco Aero 4 and the Milenco Grand Aero 4 mirrors. The clamp also fits Aero 1, 2 and 3 versions, and converts older Mirrors to fit new model vehicles. These clamps offer an outstanding and versatile system, which is engineered to fit most current (post-1995) cars, 4x4's and vans. The Aero clamp system has easy to use thumb wheels on a tilting axis, which enable the clamps to 'shape' to the contours of the vehicles mirror, allowing 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. Use the Aero clamps on Aero 1 and 2 versions which will convert older mirrors to fit a wider range of newer vehicles. The clamps are made of a high-quality product and are manufactured with the highest quality materials available. The mirror screws are high-grade stainless steel and turn in brass inserts that won't corrode. An ideal replacement or upgrade to your Aero mirrors.
