A series of hingedly connected spanning panels is provided. Each spanning panel includes two opposing outer edges. Alternating ones of the spanning panels include a raised ridge disposed along each of the outer edges of the spanning panel. At least one sleeve is disposed along each of the outer edges of a plurality of the spanning panels. A plurality of elongated rods are provided. Each of the rods is configured to pass through a plurality of the sleeves, the rods thereby maintaining the spanning panels in a substantially fixed linear relationship to one another. An end panel is hingedly connected to each end of the series of hingedly connected spanning panels. Each of the end panels is substantially wedge shaped and includes a gripping surface.
