A contractor from Los Gatos, CA says:
hello, pls could you tell me the full owning distance of the window crank for use on an awning window. The maximum load it can support and if there are any technical drawings available for the 39-015. Thanks for your help, Steve

The 39-015 Roto Gear Window Crank Awning Window Operator has an approximate sash opening of 14 1/2". I do not have a maximum load for this awning window crank operator. Take a look at the included picture for a more detailed drawing of this window crank operator.

I own Anderson awning windows. Right now they only open about 8 inches. I don't get any air flow...will this operator work with my windows?

Awning windows normally don't open too far. With that being said, the 39-015 could get your window to open up a bit farther. However, you will need to have room to install it in your window. You could have a problem trying to convert the Andersen operator over to a Truth operator. I have never tried it, but if you do, don't forget the brackets 39-170 and the 39-114L handle. Those parts will also have to be replaced.
