  • Patent number: 6688426
    Abstract: A device for allowing a user to selectively extend and retract wheels at the feet of an A-frame stepladder thereby enabling the user to move the ladder from point “A” to point “B” without physically moving, lifting or dragging the ladder. The apparatus includes a gear assembly at the foot of each ladder siderail having an attached caster-style wheel. Each gear assembly is mechanically associated with a handgrip trigger mechanism located along the ladder siderail in a position convenient for the user to operate with each handgrip trigger mechanism controlling the two gear assemblies on the same side of the stepladder.
