Nifty, well constructed stainless steel shelf box
Easily makes a small, tip out tray to make use of the normally "dead space" behind the false cabinet door in front of the kitchen or bathroom sink. All that is needed are a couple of cabinet hinges for the bottom of the false door, one of these nifty metal boxes, and something to halt the forward movement of the new tip out shelf (a chain, a special stop-hinge, or a cross bar that is stopped by the cabinet frame). A small drill for pilot holes (if even necessary) and a screwdriver are all the tools needed.
This stainless steel (SS) box mounted to the back of the false door with two SS wood screws forms a perfect tray for small items such as sponges, nail brushes, and other little things. The hinges allow the false cabinet door to tip forward to expose the open top of the SS box for storage. I opted to use a thin metal cross-bar extending wider than the drawer frame, attached to the back of the box with two small SS bolts and nuts, to form a simple stop to keep the box's contents from spilling onto the floor. This 30-minute DIY project works perfectly and looks completely built-in to the cabinet design. Highly recommended!
