The Rhino Pool Pad can add years of life to your pool and its liner. Our durable Rhino Pool Pad is made from a special cloth fiber made up of 45% post consumer and 45% industrial recycled material. The Rhino Pad acts as a vapor barrier to keep potentially harmful water away from metal components. In addition, liner failure due to puncture is minimized and heat retention is improved. A smooth, easy to clean bottom and reduced indentations are just a few of the benefits of using a Rhino Pool Pad. The Rhino Pad is .125 or 1/8 of an inch thick.
