摘要
An apparatus attachable to an extension ladder is provided having a single leg extendable in a direction perpendicular and adjacent to the two lowest rungs of an extension ladder, a channel bar sized to receive a substantial length of a lowest rung of the ladder, and a hook for latching onto a next to lowest rung of the ladder. A foot pivotally mounted to the leg at one end thereof supports the leg onto or at least partially into a level or non-level surface. A step member extends from the leg at an angle. When the ladder is extended upwards by a user, a removable arm member is received through a holder of the leg to lie against a user's leg to provide stability and prevent spinning. The apparatus when attached to the lowest two rungs elevates the ladder to be non-contact with the level or non-level surface.
