This invention provides a retractable, pivotable, slidable, and removable horizontal bar device designed for containing a cover to shield the rear compartment of an automobile from view. The bar also provides for securely holding in place conventional plastic bags when such bags, filled with groceries or other items, are being transported in a vehicle, maintaining the bags in an upright, suspended position on or above the floor of the interior trunk or cargo compartment of an automobile. A pair of the bars and holding systems may be used to further provide a detachable and removable cross support bar and dual covers to cover the entire rear compartment of an automobile.
