Abstract
Abstract A drawer assembly comprising back and side wall panels of extruded construction each comprising upper and lower hollow sections interconnected by a web defining a longitudinal recess which, in the drawer side wall panels, is adapted for engagement with drawer runners mounted in a cabinet or the like in which the drawer is to be supported in use, the wall panels being interconnected at right angles to one another by corner pieces having projections engaging in the open ends of the upper and lower hollow sections of the panels, and stop devices slidably mounted on said web at opposite ends of the back panel for movement between retracted inoperative positions in which the stop devices are clear of the longitudinal recesses of the side wall panels and extended operative positions in which portions of the stop devices project across said recesses for engagement with abutment members carried by the drawer runners.
