The cart includes a body having a front wall with an opening. Tracks for a plastic shutter-type door are located at either side of the opening. The end portions of the articulately interconnected members making up the door are received within the tracks. Each end portion has a protruding lip. Each track includes a pair of spaced members, one of which carries a lip which extends towards the surface of the end portion. The end portion of the door is received between the track members with the lip on the track member situated between the lip on the end portion and the wall opening. The lips interengage to prevent removal of the door from the track. A rigid insert is received within a slot extending along the length of each door member so as to reinforce same.
