发明名称 Roof step system
摘要 A step system for providing a toehold/slide guard on inclined surfaces, such as a roof is disclosed. Individual steps including a toehold are connected at variable distances by flexible material permitting the steps to be spaced sufficiently far apart to allow an adult to kneel between neighboring steps. In preferred embodiments of the step system, individual steps include molded cutout handles, reenforced grommets for passage of fasteners, and non-skid surfaces for additional safety when the step system is employed in steeply pitched planes.
