Double hung latch and jamb hardware
A fenestration operation hardware assembly includes latch mechanisms configured for coupling to respective top and bottom sashes, and a paddle member configured for coupling the latch mechanisms. The latch mechanisms include movable latch bolts, and at least one of the latch mechanisms includes an operator interface feature movable between at least initial and operating positions. In an initial position, the latch bolts are in respective projected positions, and the top and bottom panels are immobilized. In a first withdrawn position, at least one of the top and bottom panels is movable, and in a second withdrawn position, at least one of the top and bottom panels is tiltable. In an example, a top latch bolt is moved by the paddle member according to movement of the bottom latch bolt.
