Installation is achieved by tightening the bar clamp onto the side of the bath tub. No tools are required and no damage is done to the bathtub.
This product provides support for people with balance problems who are in peril when stepping into or out of a bathtub. It is not designed to have a lot of force exerted on it in a sideways direction. People who require a bar that will support a lot of force should be considering a properly installed wall bar.
