Using this grab bar is simple. First, choose a suitable location on a wall where you need support. Then, use No. 10 self - tapping screws or oval head mounting screws (not included) to install it through the predrilled holes in the flanges. Make sure to align the holes well for a secure fit. When using the grab bar, hold it firmly to avoid slipping. As for maintenance, you can clean it regularly with a mild stainless - steel cleaner. Wipe it dry to keep the satin finish looking good and prevent water spots. Do not use abrasive cleaners as they may scratch the surface. Also, check the mounting screws periodically to ensure they are still tight. If you notice any signs of wear or damage, it's a good idea to replace the grab bar to maintain safety.
