Abstract

Abstract A security device designed for protecting the shackle of a disk shaped padlock when mounted on a door of a container which consists of a housing for an armor protected latch bar which housing defines a recess providing access to an aperture in the bar by a circular shackle of the padlock. The recess also encases most of its housing exposing only the key tumbler of the lock which if tampered with will not cause movement of its concealed circular shackle. The latch bar is at least partially covered with a high carbon steel at the point it extends into an associated keeper.
