ABSTRACT:
A ladder conversion kit for converting an extension ladder into a stepladder. The kit includes one or more pairs of support braces for holding the two ladder elements together to form the stepladder. In a first embodiment, there is a top pedestal unit with a supporting surface and four sleeves with clamps that hold the pedestal onto the side rails of the ladder elements. In a second embodiment, the pedestal has four slots in the supporting surface, through which the upper ends of the side rails fit, and bungee straps are attached to the supporting surface and hook onto rungs of the ladder elements. In a third embodiment, there is no pedestal, and the ladder elements are held together solely by the support braces. The support braces may clamp onto the side rails or rungs of the ladder elements, or, if the rungs are hollow, they may be attached to rods inserted through the rungs. If there is more than one pair of support braces, they may be of different lengths, so as to attach to and hold the ladder elements at different locations. The support braces are adjustable in length. For each embodiment, a paint tray and storage container for components are optionally included with the kit.
