Abstract: A rolling ladder includes opposing side members between which a plurality of treads are disposed at predetermined locations to define a ladder. The ladder further includes a support structure coupled to the ladder and including a front wheel support coupled to a plurality of rolling devices. A leg assembly has a user-adjustable length leg, allowing the user to extend or retract either leg to accommodate uneven or irregular floor surfaces. The leg length may also be adjusted to allow for wear in the material of the leg. A lock mechanism is responsive to user actuation and is configured to move the rolling devices from a rolling position to a retracted position, wherein the leg of the leg assembly contacts the floor to thereby inhibit movement of the ladder.
