For installation, use No. 10 self - tapping screws or oval head mounting screws (not included) to secure it through the predrilled holes in the flanges. Make sure to place the screws about every 120 degrees for a secure fit. Note that the mounting hardware will be visible after installation. To maintain your grab bar, wipe it down regularly with a soft, damp cloth. Avoid using abrasive cleaners as they may damage the satin finish. This grab bar is built to meet or exceed ADA standards, so you can trust it for long - term, reliable use.
