ABSTRACT:
A latch is disclosed which is both rugged and economical. The latch includes a flanged housing which acts as a bushing for a journal portion of an operator. The operator includes a narrowed and recessed handle portion. At the inner end of the operator, a generally planar striker is placed to the interior of a door to interact with the frame. The striker rotates with respect to the housing and is limited in rotation by a stop which interacts with the housing. The striker is secured to the operator by connector means to prevent relative movement between them. The housing is fixed to the door by securement means which draws the flange of the housing against the exterior of the door.
