Abstract:
The present invention is used on stepladders that are structured to provide improved lateral stability, step support and equipment/supplies support for stepladder users. The stepladder may have a step element and a support element rotatably attached at a top platform or a first step element rotatably attached to a second step element adjacent a top step. A hinged strut may be attached at opposed ends between the opposed elements intermediate the ladder top and the ladder base. A plurality of steps may be spaced apart and attached between step rails of step elements. A lateral support leg may be rotatably attached at a top end to each of the step rails intermediate a second step and a third step from the ladder top and a hinged leg strut may be attached at opposed ends between each of the support rails and lateral support legs.
