[Adjustable Mounting Hole Pitch] The mounting position of the upper bracket can be adjusted, allowing for a pitch of up to 800mm between the upper and lower brackets. You can utilize existing screw holes, eliminating the need to create extra screw holes in your bathroom tiles. The drill bit diameter is φ6mm, with a pilot hole of 40mm. [Height and Angle Adjustment] The total length of the slide bar is 820mm. You can adjust the height of the showerhead by sliding the hook up and down. The spray angle can be adjusted 360° by rotating the hook. With a simple lever operation, you can use the shower at your preferred height and angle, creating a comfortable bathing experience for the whole family. [Split Structure] The slide bar uses international standard stainless steel and features a split design. The hook and other parts are made of high-strength ABS material, making them lightweight and easy to install. *Be sure to rotate the bar in the direction of the body to connect it. Please note that if the rotation direction is incorrect, the bar will not connect. [Special Plating Finish] A multi-layer nickel-chrome plating process is applied. The nickel plating layer provides excellent corrosion resistance and adhesion, while the chrome plating layer is resistant to scratches, ensuring a sparkling surface even after years of use without the plating peeling off. [Easy Installation] A parts package is included for easy installation, allowing you to use the shower freely. Installation is easy even for beginners.
