  • Patent number: 5199579
    Abstract: A multiposition shelf attaching is disclosed, which device is adapted for use with shelving standards or with wire-grid walls. The device is a wire formative and is constructed from either a round or a square wire extrusion. The anterior portion of the device, when installed in a first position, that is, usually with the shelf-being-attached horizontal (or normal to the face plane of the grid or standard), lies in a plane substantially parallel to the face plane. The posterior portion has two or more clips or stops connected serially to the anterior portion. Each clip has a load-bearing portion and a descender portion connected at substantially right angles to the load-bearing portion. When installed, the load-bearing portion of the selected clip means rests upon the lower edge of the opening in the standard or grid and the descender abuts the rear plane thereof.
