Pair of Sticky Pads: When Suction Cups Need Help

• 2 clear smooth discs: 2.5" diameter
• 2 super-adhesive sticky pads: traceless, washable & reusable. 

Installation Tips
First, be sure your shower rod is set at the right height and your SPACE System is suitably installed. When you open the window fully wall-to-wall, look at where the suction cups touch the wall. Remember those two spots. Now peel and apply a sticky pad on each spot. Then apply a disc on each. They’re very sticky, so aim carefully. The disc will now offer a smooth surface on which the suction cup will stay. See these images on the product description here.
