Using this grab bar is easy. First, decide where you want to install it. Then, use the predrilled holes in the flanges to attach it to the wall with No. 10 self - tapping screws or oval head mounting screws (you'll need to buy these separately). Make sure to place the screws evenly according to the 120 - degree spacing of the holes for a secure fit. When using the grab bar, hold it firmly on the non - slip peened surface to avoid slipping. As for maintenance, wipe it regularly with a soft cloth to keep the satin finish looking good and to prevent fingerprints. Avoid using abrasive cleaners as they may damage the finish. If you notice any loose parts or damage, check the installation and make repairs as needed. This grab bar is built to last, but proper care will ensure it serves you well for a long time.
