A ladder stabilizing system having a solid brace (50 or 46) or the combination of side spreaders (24C), the ladder sections (10 and 12), and a diagonal cross brace (18) creating two rigid triangles, the function of which is to prevent the ladder sections from twisting or flexing and therefore make the step ladder or the side braces (70 & 74) of a ladder or step ladder much more stable and will prevent the ladder sections (10 and 22), or extended side braces from twisting or flexing, thereby making the ladder stronger and safer.
