Using this grab bar is simple. First, decide where you want to install it. Make sure the surface is flat and sturdy. Take your No. 10 self - tapping or oval head mounting screws and insert them through the predrilled holes in the flanges. Tighten them well to ensure the grab bar is secure. When using it, just hold onto the bar firmly. It's designed to give you a non - slip grip. As for maintenance, wipe it down regularly with a soft cloth. This will keep the satin finish looking great and prevent fingerprints from building up. Avoid using abrasive cleaners as they might damage the surface. Also, check the mounting screws every once in a while to make sure they're still tight. If you notice any issues, like the bar feeling loose, tighten the screws right away.
