ROTARY LATCH FOR SCREEN DOOR ABSTRACT OF DISCLOSURE This invention relates to a rotary type latch for sliding screen doors wherein the rotary member is molded from a plastic material such as a polycarbonate and which is rotatable in either direction for universal application to either right hand or left hand door operations. The rotary latch engages a slot in a door pull molded from a similar plastic material and contacts the screen door frame through the slot to cam the door against a retaining channel mounted on a door frame. The rotary latch includes a plurality of flat cam faces affording multiple locking positions and which necessitate positive lock rotation to enable the latch to be disengaged. This latch mechanism is of particular usefulness for application to sliding patio screen doors where the screen door closes into a pocket within the side iamb of the patio door frame.
