Abstract: A modular storage tray assembly is attached to a wall by means of a headpiece with two pins spaced a predetermined horizontal distance apart. A number of tray assemblies are suspended in series from the headpiece by means of these pins. Each tray assembly has a horizontal tray, a connecting member adapted to removably attach to the pins of the headpiece or to the tray assembly immediately above, and a pair of pins on the edges of the tray to permit attachment of the next tray assembly below. The spacing between each pair of pins is substantially uniform, so that the tray assemblies can fastened together in any order. Removable dividers can be inserted to divide the trays into separate compartments. A frame with a number of forward-extending members can be added below the bottom tray assembly to hang necklaces, bracelets or rings.
