ABSTRACT:
A wheeled dolly or support for a ladder is made in two pieces, including a base plate that permanently affixes to an outside surface of a rail of a ladder, and a frame that is removably mounted on the base plate. The frame carries wheels that will support the ladder when the ladder is placed on edge and one end of the ladder is lifted. The frame normally is near a base end of the ladder. The frame that holds the wheels can be removed when desired for storage, or for use in a location where the wheels may restrict clearance around the ladder.
