Window lock for a sash window assembly
The sash window assembly includes an upper sash window and a lower sash window. Each of these windows are mounted within opposed guide rails on a master frame. At least one of the windows is slidable within the frame relative to the other window. The window latch system includes a locking assembly for mounting on one side of the sash window. The locking assembly is designed to engage a keeper on the adjacent side of the other sash window. The locking assembly includes a housing having an extended hollow central shaft, an actuator arm, and a cam having a latching blade for engaging the keeper. Alignment pins or tabs are located on the bottom of the housing. A single retaining screw extends through the extended hollow central shaft and secures the housing to the window.
