An RF-remote control, retrofitted, self-contained, automatic window opener is provided for casement windows or the like which includes a housing having a DC motor therein which has a power shaft extending therefrom. The DC motor is powered by a battery source contained within the housing. The power shaft of the DC motor is selectively removably secured to the drive shaft of a conventional casement window opener mechanism so that the DC motor may rotate the drive shaft in either direction to open or close the sash of the casement window. The window opener of this invention is mounted within a housing which has anti-rotation members selectively adjustably extending therefrom which engage the window frame to prevent rotation of the unit when the motor is activated. The unit includes an electrical circuit which has an RF receiver associated therewith which is controllable by a remote RF transmitter to enable a person to remotely control the opening and closing of a casement window.
