A lock is described which is adapted for use in combination with a conventional latching handle assembly mounted on the bottom panel of a roll-up door mounted on a truck or the like. The lock includes a laterally movable dead bolt which, when locked, is in the pivotal path of the latching handle assembly thereby preventing the latching handle assembly from being moved to its unlocked position. A counter is also associated with the lock which visually indicates the number of times that the lock has been actuated.

Roll-up door lock

A sequential seal for use with a roll-up door positioned in a truck or van body and which indicates the number of times that the door has been moved from its closed position towards its open position. A sequential counter is mounted in the door and is actuated each time the door is moved from its closed position towards its open position.
