An extension plank has first and second elongated sections that telescope from a plank maximum length to a minimum length. Such sections have an outboard portion and an inboard portion joined by a plurality of parallel tubular elements of rectangular cross-section. The outboard portion includes an elongated U-shaped channel and the outboard ends of the tubular elements are fixed into the U-shaped channel spaced apart from each other. The inboard portion includes a pair of straps and a plurality of U-shaped guide saddles. The straps are fastened to each of the tubular members with a guide saddle sandwiched therebetween. The inboard portion of the first elongated section slideably encloses the tubular elements of the second elongated section and the inboard portion of the second elongated section slideably encloses the tubular elements of the first elongated section whereby the elongated sections can telescope with each other and the guide saddles provide free, easy sliding action between the elongated sections.
