Using the ASI 3801 - 18 grab bar is simple. Just install it on a flat surface following the provided instructions. When using it, hold it firmly for support. Make sure the surface you're mounting it on is strong enough to bear your weight. As for maintenance, wipe it with a soft, damp cloth regularly to keep it clean. Avoid using abrasive cleaners as they can scratch the satin finish. Check the flange covers and mounting hardware periodically to ensure they're secure.
