Abstract: A display rack on a store aisle is mounted to upper and lower frames which are adjustable in length along the aisle and adjustable in depth perpendicular to the aisle to mount the display rack at a desired location along the aisle and perpendicular to the aisle. The frames are each fastened to two posts adjacent the aisle, using a rear member of each frame to connect to the posts. The frames have front, rear and end members that may be disassembled for shipment, and that are each adjustable in length. The display rack is filled with merchandise before it is fastened to the frames.
