Suction-grip assist bars give you extra confidence! Chrome-finish handles instantly secure via two suction cups that form an ultra-strong seal for a stable grip every time you step out of the bath or shower. Grip can be mounted either vertically or horizontally without holes, tools or permanent installation. They install and release with just the flip of a level. Thanks to the red and green color indicator buttons, you'll know at a glance if you have a secure suction. Small 4-1/2"W x 11-1/2"L x 3-1/4"H. Large 4-1/2"W x 16"L x 3-1/4"H.
