摘要： A pair of substantially parallel lengthwise spaced apart two layered web straps having an attaching device integral at one end of each corresponding web strap. At designated intervals along each web strap, the two layers are spaced apart to form an opening through which a ladder step is inserted at each end of the step. A flanged end cap is removably attached to each end of the ladder step along an outside edge of the web strap. The end caps are removed from the end of the ladder steps and the ladder steps are removed from the straps for compact storage with the straps.
