This disclosure depicts a plug-in module card holder for supporting a plurality of circuit cards, each of the cards having a securing level with a notch. The plug-in module card holder comprises at least two card shelf plates and a strengthening strip for each of the card shelf plates. The card shelf plates are oriented in a parallel relationship and each has one or more grooves. A circuit card is retained in one of the grooves in each of the two card shelf plates. Each of the card shelf plates has an outer edge having a tab with first and second offset channels. The strengthening strip has an engaging portion consisting of first and second offset ridges for engaging the first and second channels of the tab of the card shelf plate. The strengthening portion also has a retaining portion for mating with the notch in the lever and thereby securing the circuit card in the circuit card holder with a cam action.

A clothes hanging apparatus is secured to the underneath of the shelf in a closet to provide additional rigidity to the shelf and to provide a hanger for suspending clothes therefrom. This clothes hanging apparatus is generally secured to the underneath of the shelf by a series of intermediately located mechanical fasteners, but other fasteners are equally suitable. As a result, this apparatus may be secured to a mid-region of the shelf; it need not extend the entire length of the shelf as other systems require. Additionally, this apparatus is preferably of unitary construction and of uniform composition.

A combined shelf and hanger bar system which is easy to install and has a neat appearance makes use of end brackets having wall plates for securement to closet end walls, inwardly projecting walls defining ledges to support the ends of a shelf panel, and pockets to receive and hide the ends of front and rear rails stiffening the longitudinal edges of the panel, the front rail also having a depending portion providing a hanger bar.

A shelf includes a plurality of integrated hook members supporting a rod member to provide free movement of items supported by the rod member. The hook members are integrally connected to support members of the shelf deck to support the rod member for use in, for example, hanging items thereon.

The present invention provides a clothes hanger rod attachment to be used in combination with wire shelves so as to allow uninterrupted slidability of clothes hangers while retaining strength, durability, low cost, and ease of manufacture. The attachment may be readily used in conjunction with existing wide web and narrow web wire shelving configurations.
