Using this grab bar is easy. First, find a suitable location on a wall in your commercial bathroom. Drill holes according to the screw holes on the concealed mounting flange. Insert the concealed anchors into the holes and then attach the grab bar using the screws. When using it, hold onto it firmly for support when getting in or out of the bathtub or when standing up from the toilet. For maintenance, simply wipe it with a soft cloth and mild soap regularly. Avoid using abrasive cleaners as they can damage the peened finish and the satin - finish stainless steel. Check the screws periodically to make sure they are tight and the grab bar is secure.
