DESCRIPTION Enlarge Viewing Area: Our 10.5"L x 4"H marine mirror provides a larger viewing area. Suitable for sealed or unsealed pontoon railings or bimini top with diameters not exceeding 1.7 inches. Please note it is not suitable for boat windshields. Stable And Reliable: Our upgraded ski boat rearview mirror is fixed with an aluminum alloy tube clamp, which is more rust-resistant and aging-resistant than a plastic tube clamp. In addition, the metal tube clamp has a better bite force and better fixation, preventing slipping. 360° Adjustable At Will: This enlarged boat rearview mirror has a unique 360° rotatable ball head structure and gear design, allowing you to adjust the viewing direction of the mirror surface and the tilt angle of the bracket according to your needs. 25.59-Inch Stainless Steel Extension Pole: Compared with the limited view of the mirror directly clamped on the windshield, the mirror with a support rod allows you to see the surrounding waters and other boats clearly and unobstructed, providing an unparalleled viewing experience. Versatile Use: Kemimoto marine mirrors are perfect for a wide range of water activities, including family outings, fishing, water skiing, and diving. Whether you're relaxing with the family or enjoying exciting water sports, Kemimoto marine mirrors offer comprehensive support and protection. FITMENT Compatible with sealed or unsealed pontoon railings or bimini top with diameters not exceeding 1.7 inches. Please note that it is not suitable for boat windshields
