Abstract: A collapsible cover system and kit therefor are removably mounted to a plurality of spaced stake sockets secured between longitudinally extending rub rails and opposite sides of a flatbed vehicle. Stakes, disposed in the stake sockets, are slidingly connected to two lengths of spaced guide tracks that project above and extend along the sides of the flatbed vehicle. Inverted bow-shaped members having free ends are removably secured to carrier means that slidingly connect the bow-shaped members to the guide.
