This 12" suction cup grab bar by Drive Medical allows the added versatility of installation at any angle. It can be installed and removed without the hassle of tools or a service professional, allowing the product to be used right out of the package. The large suction cups are 3.75" in diameter and provide an extremely strong hold. Release levels make attaching and detaching the bar a cinch. A Red/Green color indicator shows you whether installation was "safe secure" or if you must "re-affix" the grab bar. The grab bar is to be used to assist with balance only and not to be used to leverage body weight. The product is protected by a limited lifetime warranty.
