ABSTRACT:
A permutation lock is mounted on one of a pair of hinged sections and is adapted to receive and lock to a hasp of the other section. The lock includes a plurality of rotatable dials which act against a movable bolt to move a latching end of the latter toward and away from a locking position. Even with the dials in a locked mode, the bolt can be moved to an unlocking position in response to introduction of the hasp into the lock. The hasp includes a completely closed aperture which is adapted to receive a pair of hooks at the latching end of the bolt.
