A platform shipping rack cart for shipping rack(s) supporting glass sheets is provided. The cart may include a plurality of upwardly extending locator projections (e.g., pins) for engaging L-frame racks that hold glass sheets, so as to allow the L-frame rack(s) to be positioned and securely mounted on the cart for shipping and the like. The locator projections are arranged so that first and second L-frame racks may be provided on the cart either facing each other, or in back-to-back position, as desired. The cart advantageously allows multiple L-shaped glass racks to be stabilized on the cart and moved at a given time, and allows for loading the glass in either lengthwise or sideways orientations into vans or the like.
