Abstract
A scaffold includes first and second ladder frames. Each ladder frame includes a first and second vertical supports, a center support, rung(s), and upper and lower horizontal supports. The upper horizontal support is formed of tubular material, and has a central section and flattened end sections mounted to corresponding vertical supports. The center support and/or rungs advantageously have coped and slightly flattened end sections. Recesses formed by the flattened end sections provide space to partially receive vertical or horizontal supports of another ladder frame when the frames are stacked, thereby reducing overall stack height.
