A lockable window, and a manual control for a lockable window. The window includes a window sash having a first locking member and a window frame having a second locking member mounted thereon for movement between a locked position cooperating with the first locking member for locking the sash to the frame when closed against the frame and an unlocked position clear of the first locking member to allow movement of the sash relative to the frame. The frame also has an opening therein for allowing access to the second locking member from an interior side of the frame. The lock control has a housing including an enclosure open on one side with a flange around the open one side, the housing being mounted with its enclosure substantially in the frame opening and its flange on the interior side of the frame. A handle is pivotally secured in the housing enclosure and includes an opening at one end. A hard, resilient plastic retainer substantially surrounds the frame opening and is disposed between the frame interior side and the housing flange to substantially seal against leakage through the frame opening to the frame interior side. The retainer further includes a flexible hook portion received in the handle opening when the handle is in the locked position, where pivoting the handle out of the locking position requires a pivoting force sufficient to flex the hook portion clear of the handle. The hook portion is adaptable for use with both right and left hand operation. The handle is operably connected to the second locking member so that pivoting of the handle between locking and unlocking positions selectively moves the second locking member between the locked and unlocked positions.
