The lock body can be mounted to the equipment and the chain can be bolted or welded to the door or hatch with the proper amount of "slack" for the latch bolt to reach the DM lock body.

Under normal conditions the key is upstream in the interlock scheme and the latch bolt is trapped in the lock securing the door in the closed position. The latch bolt cannot be released until the key is inserted and turned. Only then can the latch bolt be rotated ¼ turn and released from the lock thereby trapping the key. The door or hatch must be closed and the latch bolt must be returned to the lock body in order to free the key.

The DM housing and cylinder are made of brass. The latch bolt and chain assembly are made of 316 stainless steel.
