Abstract

Abstract A high security lock totally encloses the projecting portions of a hasp and keeper. A protective outer cup-shaped housing surrounds, and is rotatable about, a lock body which fits over the projecting face-to-face hasp and keeper. A heavy bolt is movable in the body to a dead-locking position through the hasp and keeper, and is controlled by a key operated lock core mounted in the body and accessible only by an elongated key inserted through a guard plate in a constricted key hole in the outer housing. Hardened steel plates and pins in the lock body protect it from drilling and cutting.
