Using the ASI 3875 grab bar is easy. Just mount it on the wall at the desired location using the provided mounting hardware. Make sure to place it at a height that's convenient for you to hold. When using it, always grab it firmly to ensure your safety. As for maintenance, simply wipe it with a soft, damp cloth regularly to keep it clean. Avoid using abrasive cleaners as they may scratch the satin finish. If you notice any damage to the flange covers or the bar itself, check the mounting and make repairs as needed to keep it in good working condition.
