ABSTRACT OF THE DISCLOSURE This is a cover assembly for open truck boxes in which a pair of longitudinally extending guides are situated one upon each side on the upper edges of each of the sides of the truck box. Means similar to a roller blind device are situated at one end of the truck box and the flexible cover is rolled onto this roller and the spring therein normally maintains the cover upon the roller. Cables run through each edge of the cover and are secured therein and these cables together with the cover surrounding same are engaged within the guide means on the side of the box to guide the cover when extending and retract- ing same and to maintain the side edges of the cover in engage- ment with the guide means. The cable extends over pulleys at each end of the guide means and is connected to a winch for pulling the cover outwardly against the spring pressure of the roller. When the winch is reversed, the spring pressure of the roller rolls up the cover and stores same until needed.
