An improved tool box adapted to be positioned onto a joist or beam. The tool box has a central passageway extending between and through its front and rear walls. At least two web cross members extend between the side walls of the central passageway. Each of the web cross members have a plurality of generally rectangular shaped cutouts positioned along a common longitudinal axis, each of the cutouts communicating with each other. Each cutout has a width that is greater than the width of that cutout located immediately above it. The cutouts form upper joist receiving raceways. A lower joist receiving raceway is formed by the first and second bottom edges of the web cross member and that portion of the side walls of the central passageway located below the bottom edges of the web cross member.
