Abstract
A ladder kit comprises a plurality of parts from which a ladder may be constructed. The parts of the kit may be selected and assembled in a number of ways, resulting in various types of ladder structures. The main components of the assembled ladders include elongated tubular side rail sections and rectangular frame sections. The frame sections fasten the side rail sections into coplanar pairs and form the rungs of the ladder.
