Aluminum cat climbing ladder - heavy-duty design, easy access to roofs and high walls This portable aluminum ladder is ingeniously designed, lightweight and space saving, as flexible as a cat climbing. It can perfectly fit the edges of exterior walls and roofs, making it convenient for you to clean drainage ditches, repair exterior facades, or inspect attic vents. The stable boots and tool straps on both sides of the deep steps and box type guide rails can be used for climbing two floors, and then the entire span can be folded to the length of a truck for easy transportation from one location to another. No rust, no collapse, moderate height, no damage to the wall, quick installation, and can be placed flat against the wall for storage after work.
