These suction cup turtle ledges are great for providing a basking dry area in your aquatic turtle habitat. It is imperative for many species of turtles such as:

Red/Yellow Eared Sliders, Map turtles, Spotted Turtles, Painted Turtles and many other chelonians. Not only does this provide an essential turtle dock for UVB basking (since water reflects UVB light) this allows your chelonians to absorb in the sunshine throughout the day.

You can also use these ledges as a beginner platform for hoisting of different woods/rocks for a more unique basking spot.
