Abstract
A casement sash locking system including locking assembly, drive assembly and lock strike that can be mounted on either side allowing the window to open from the left side or right side. The locking assembly includes a lock catch that functions to first lift the outer free end of the sash and then pull the sash to a closed position, thereby preventing drag of the sash on the window frame sill.
