This is the ladder that provides five different functions to fit the right household task. Its three-section, locking hinge and pin design allows it to extend in 1' increments, enabling use as a step ladder, stairway ladder, or wall ladder that each range from 4' to 7'-tall. Its stairway configuration allows you to shorten one side of the ladder to accommodate a step’s riser height (ideal for hanging pictures in a stairway) while its wall configuration’s oblique angle enables close-in painting without the need to place a standard step ladder sideways against a wall. As a scaffold, two of the ladder’s three sections can be used as mini-step ladders to support a board. All three sections combined telescope to a full 17' length to form an extension ladder with a flared top and bottom for added stability. Made from aerospace engineered 6061 anodized aluminum that supports up to 300 lbs. When stored: 55" L x 23 3/4" W x 8 1/4" D. (35 1/2 lbs.)
