We have a couple of windows that crank open and are in locations that make it difficult to reach the window cranks. One is a garden window behind the kitchen sink and the other is a large window behind our extra wide jacuzzi tub, each of these windows have two window panes that crank out to open. We were hoping to swap out the manual window cranks for some sort of electronic crank system, but so far everything we've found is discontinued. Does anyone have any suggestions or know of any electronic crank systems that are still available? The windows are Anderson windows, if it would be helpful I can check for the model information on the windows and post that information as well.
