Using the ASI 3501-48 grab bar is simple. First, gather your No. 10 self-tapping screws or oval head mounting screws (not included). Then, align the flange holes with the desired mounting surface and insert the screws to secure the grab bar. Make sure it's firmly attached for your safety. When using the grab bar, hold it firmly with your hand for support. As for maintenance, you can clean it with a mild soap and water solution. Avoid using abrasive cleaners as they may scratch the satin finish. Regularly check the screws to ensure they're tight and the grab bar is secure. If you notice any signs of damage or looseness, replace or repair it immediately.
