This scaffold has a standing platform of 6′ x 30″ and has a max standing height of 6′ per section, adjustable at 2.5″ increments. Up to two sections can be stacked to give a max platform height of 12′. This scaffold can be used on stairways which are at least 32″ wide and can give a standing platform of up to 6′ tall per section measured from the lowest stair that the scaffold is set up on. We include casters, safety rails, and/or outriggers (when stacking two sections) for added safety at no additional charge. This scaffolding is for indoor use only.
