ABSTRACT:
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.
