A locking arrangement for use on an enclosure which enclosure has an opening and a roll-up door to close the opening, automatically locks the door when it is closed. The arrangement includes a striker member mounted on one side of the door to define a striker path when the door is moved upwardly or downwardly. A lock mechanism includes a dog and means for biasing the dog to removably extend into the striker path. When the door is moved downwardly, the striker will force the dog out of the striker path to thereby permit the striker to pass over the dog and for the door to extend below the dog. When the striker is below the dog and the door is moved upwardly, the dog will engage the striker and prohibit upward movement of the striker and the door.
