A section of a cable tray is adapted for being mounted on a vertical surface, like a wall, a line of columns or a soffit. The cable tray section includes an upper wall mounting section having an external wall part for being mounted to the wall, a lower external wall section which is indented from the upper wall section, having an inner wall which defines one wall of the tray. A space inside the wall mounting section receives a splice shunt block for attachment to an adjacent tray section. A tray floor section extends out from the inner wall of the wall mounting section. Various stiffeners are disclosed for the tray section floor. An outer wall extends up from the tray floor completing the U-shape of the tray section. The tray section may be an integral metal or plastic extrusion. Alternatively, it may be bent into shape from one or more sheets of metal. A splice shunt block joins adjacent wall mounting sections. In an alternate embodiment, the tray is comprised of a section inlcuding the wall mounting section and the tray floor. An L-shaped extension has one leg that lays over the tray floor. One edge of that leg is held at the inner wall or in a selected one of a plurality of slots defined along the tray floor. The other leg of the extension defines the outer upstanding wall of the tray.

A section of a cable tray for being mounted to an upstanding surface, the cable tray section comprising an upstanding wall mounting section for being attached to an upstanding surface and a tray floor for supporting cable placed on the tray floor, the tray floor being attached to the wall mounting section and extending transversely to it and away from the wall mounting section in an outward direction; the cable tray section having opposite longitudinal ends, each end adjoining the end of an adjacent cable tray section, for defining an elongate cable tray of a plurality of the cable tray sections; the wall mounting section having a top part above the floor, the top part having an external wall for being mounted to the upstanding surface to which the cable tray section is to be attached; means for mounting the external wall to the upstanding surface; the wall mounting section having an internal wall spaced outward from the external wall and also facing outward from the wall mounting section toward the tray floor, the external wall and the internal wall being attached integrally to each other and being spaced apart for defining a hollow interior space of the wall mounting section, whereby the external wall and the internal wall define a truss for stiffening the wall mounting section; the internal and external walls extending down to the tray floor; the wall mounting section having opposite ends, the hollow interior spaced of the wall mounting section being shaped for receiving a splice shunt block which extends into the hollow interior space at the adjacent ends of neighboring cable tray sections; an additional support for the cable tray section and integrally formed with the cable tray section, the additional support comprising; an integral extension of the wall mounting section extending below the tray floor; an additional strut connected integrally to the extension below the floor, extending outward from the extension and extending beneath the floor, and being spaced from the floor and extending up to contact the underside of the floor outward from the internal wall, so that the additional support is shaped for extending partway across the floor to strengthen the floor, and the additional support cooperates with the tray floor to provide a truss support for stiffening the floor; the wall mounting section, the additional support and the tray floor being integral for the truss support of the floor to transfer the load to the truss of the wall mounting section to prevent deformation of the tray floor, of the wall mounting section and of the location where they meet.
