Abstract: A tarpaulin cover for open top freight carriers having another opening at one end closed by a pair of movable doors, the cover comprising a main body portion for covering the top of the carrier secured by ties to the carrier sides and a flap portion extending from the main body portion adjacent the other opening. The flap portion includes a pair of sections each extending into the opening and inwardly of a corresponding door when closed. Each section includes an enlargement defined by a stock member carried thereby which prevents the section from being pulled out when the door is closed. The two sections are separated by an opening therebetween, each section is of a dimension less than the width of the corresponding door, and each section preferably is rectangular in shape. The sections co-operate with the doors to hold that end of the tarpaulin cover to the carrier body without ties at that end and in a manner allowing easy opening and closing of the doors.
