Each cam is provided with a latch bolt assembly engaging portion operably connected to the latch bolt assembly. The first cam further has a locking shoulder configured for selective engagement with a first lock member. A lock coupling operably connects the first lock member with a second lock member such that rotational movement of one of the first and second lock members causes rotational movement of the other of the first and second lock members. A lock knob provided on the interior side of the door is operably connected to the first lock member and facilitates toggling of the first and second lock members between the locked and unlocked positions.
