ABSTRACT:
A lock includes a case, a key cylinder mounted to an outer side of the case, and a thumb turn mounted to an inner side of the case. A deadbolt is mounted in the case and coupled with a shank of the thumb turn and operably connected to a lock core of the key cylinder. The head is movable along a deadbolt axis between a retracted position in the case and an extended position outside the case when the lock core or the thumb turn is turned. Two hooks are mounted to the deadbolt and each pivotable between a retracted, unlocking position in the case and an extended, locking position outside the case about a pivot axis perpendicular to the deadbolt axis.
