    摘要: A convertible ladder having a first ladder section and a second ladder section. The first ladder section and the second ladder section each include a pair of side rails and at least one rung that extends between the side rails. The first ladder section further includes a pair of upper rail guides and a pair of intermediate rail guides. One of the upper rail guides is attached to each of the second side rails proximate an upper end thereof. One of the intermediate rail guides is attached to each of the second side rails intermediate the upper end and the lower end. The upper rail guides and the intermediate rail guides each include a recess that is adapted to at least partially receive one of the first side rails.
