Abstract: A material handling box fabricated from sheet steel and having four generally vertical sides and a bottom wall, one of the sides being substantially open and having a hopper extending outwardly therefrom. The top of the hopper is open whereby access may be had through the open hopper top and into the interior of the box. A vertically slideable door is positioned over the opening in the side and which can be moved from a box closing position to any one of a number of vertically positioned locations to thereby expose the interior of the box to the hopper in the desired degree.
