摘要： A modular composable element for making ladders in general comprises an elongated body (1) supporting a plate-like element (11) and provided with a central portion to be coupled, at one end whereof, with a portion engageable with an adjoining modular lower element and defining, at the other end, a sleeve element (3) to be engaged with the upright portion of an adjoining modular upper element. There are further included means for locating the upright portion (7) with respect to the central portion (2), which means maxy be displaced perpendicularly to the upright portion (7) and movably locked for changing the width of the step.
