Using the ASI 3401-36 grab bar is simple. First, find a suitable place on the wall where you need support. Make sure the surface is flat and strong enough to hold the bar. Then, use the predrilled holes in the flanges to attach the bar to the wall with the appropriate screws (you'll need to buy these separately). When using the grab bar, hold it firmly to get the support you need. As for maintenance, just wipe it down with a soft, damp cloth regularly to keep it clean. Avoid using harsh chemicals as they might damage the satin finish. Also, check the screws from time to time to make sure they're still tight and the bar is securely mounted.
