DESCRIPTION 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. Hassle-Free Installation Easily install our boat rearview mirror with the thumbscrews provided, attaching and removing as needed without any tools. (Suitable for railings with a diameter of less than 1.7 inches) FITMENT Universial fit.
