ABSTRACT:
A ladder with nesting lateral support braces includes a pair of nesting braces which internally receive the pair of side support rails of a ladder during storage of the ladder. Each of the nesting braces is attached to a side rail by a hinge for rotation into and out of a support position. A support arm is provided to prevent over-rotation of the nesting braces. Each of the nesting braces may additionally include an expansible leg for use of the ladder on uneven support surfaces.
