Title: High security locking mechanism

Abstract: A high security lock to secure the eyes of a hasp and keeper. The lock is of a short cylindrical shape with a rear cavity to receive and enclose the hasp and keeper eyes, and contains a locking bolt to engage such eyes. The lock and the hasp and keeper assembly interact to give high security. The lock encloses and closely embraces the eyes of the hasp and keeper and lies close against the pads of the hasp and keeper. Shroud plates overlying the pads closely surround the rear edge of the lock. The shrouds and plates of the hasp meet those of the keeper at a separation plane offset from that of the eyes and of the door and its jamb.
