Abstract
A high security lock assembly having a tang for holding lock shackle pins,ith said tang being attached to a first member, such as a bulkhead or a door jamb. A reversible cover, which can be attached to either the left or right side of a second member, such as a door or cover, is attached, as by welding, with a hasp liner. The hasp liner has a side opening sufficiently large to clear the tang and lock shackle pins, but too small for a lock to pass therethrough. The bottom of the hasp liner is open to receive a lock which is engageable with the lock shackle pins to secure the second member with the first member. The reversible cover is provided with a flange which can be welded directly to a door, cover, or hinge.
