Using this grab bar is simple. Just find a suitable location on the wall where you need support. Then, use the predrilled holes in the flanges to attach it with the appropriate screws (you'll need to get them separately). Make sure to tighten the screws well for a secure installation. When using it, hold onto it firmly for support. As for maintenance, you can clean it with a mild soap and water solution regularly to keep it looking good. Avoid using abrasive cleaners as they might damage the satin finish. Also, check the screws periodically to ensure they're still tight and the grab bar is secure.
