Abstract: A movable ladder support device, and a ladder which includes that support device. The support device includes a rotatable member such as a wheel housed within the U-shaped section of the support device. The support device is attached to the rail of a ladder. The support device enables the ladder to be vertically repositioned against the surface of an inclined wall without the need to first remove the ladder from the surface.
