This 19 3/4" suction cup grab bar by Drive Medical is a dual rotating grab bar, allowing you the added versatility of adjusting the bars to multiple angles. Installed and removed without the hassle of tools, allowing the product to be used right out of the box. The large suction cups provide an extremely strong hold. Release levels make attaching and detaching the bar a cinch. A color indicator shows you whether installation was "safe secure" or if you must "re-affix" the grab bar.
