ABSTRACT:
A break-away door lock assembly for use in minimum security areas. The assembly consists of a door lock keeper assembly which includes adjustable pressure pads bearing upon and maintaining a door lock keeper plate in proper coactive position. Thus, the pressure structure can be pre-set to enable opening of the locked door by application of some extraordinary pulling force when occasion might arise that there is no key, or that the door is locked from the inside or the like, and it is necessary to open the door immediately.
