A fold down operator ( 10 ) for a rotatable spindle ( 224 ) of a window assembly ( 200 ) includes a hub ( 12 ), a handle ( 48 ), and a lock structure ( 300 ) ( 400 ) ( 500 ) ( 600 ) operably connected between the handle ( 48 ) and the hub ( 12 ). The hub ( 12 ) has an arm ( 32 ) and a receiver ( 22 ) adapted to connect to the spindle ( 224 ). The handle ( 48 ) is pivotally connected to the arm ( 32 ) of the hub ( 12 ), and is pivotable between a closed position and an open position. When the handle ( 48 ) is in the open position, the handle ( 48 ) is adapted to be manipulated to rotate the hub ( 12 ) and the spindle ( 224 ). The lock structure ( 300 ) ( 400 ) ( 500 ) ( 600 ) is operable to selectively lock the handle ( 48 ) in the closed position.
